Every Muslim agrees on the fact that the Holy Qur'an came down as a revelation to the Prophet Muhammad (PBUH&HP) in Arabic as we see in the following two verses:
The Holy Quran 43:3
"Surely We have made it an Arabic Qu'ran that you may understand."
The Holy Quran 12:2
"Surely We have revealed it-an Arabic Qu'ran-that you may understand."
Today with uncountable nationalities embracing the fold of Islam, many read the Holy Qu'ran in their native tongue and thereby pose different questions and arguments about reciting it in their own tongue.
These arguments include the following:
1. It is not wajib (Obligatory) to read the Holy Quran in Arabic because it is not specifically mentioned in the Holy Qu'ran that we must read it in Arabic.
2. Non-Arab Muslims do not understand the Holy Quran in it's revealed language and since Islam is a way of life, then it is more important to understand the injunctions, clear signs, stories of the Holy Prophets (AS) of Allah to gain guidance from these instead of spending time; learning a language, reciting in that language that they believe does not benefit them and that the time in which they would be occupied in reciting a language that is, they feel, not of use to them, then this time although not exactly wasted can be put to better use in acquiring actual knowledge.
Some argue that they can not learn Arabic because they are not good with languages and others still insist that while they read the Holy Quranic interpretations in their native language in the holy month of Ramadan, they have actually completed an entire Quran that month.
And a final argument given is the following:
"I do not understand at all why the Quran should be read in Arabic? Yes, Allah Almighty has said that we sent the Qur'an in Arabic for you to think about, but if we read the Qur'an in Persian, can we not think about it?"
So let's begin to answer these arguments by going directly to the Holy Qu'ran where the word Arabic is mentioned exactly ten times and see what Allah is telling us.
In the Holy Quran 12:2,
"Surely We have revealed it-an Arabic Quran-that you may understand."
In the Holy Quran 13:37,
And thus have We revealed it, a true judgment in Arabic, and if you follow their low desires after what has come to you of knowledge, you shall not have against Allah any guardian or a protector.
In the Holy Quran 16:103,
And certainly, We know that they say: Only a mortal teaches him. The tongue of him whom they reproach is barbarous, and this is a clear Arabic tongue.
In the Holy Quran 19:97,
So We have only made it easy in your tongue that you may give good news thereby to those who guard (against evil) and warn thereby a vehemently contentious people.
In the Holy Quran 20: 113,
And thus have We sent it down an Arabic Quran, and have distinctively set forth therein of threats that they may guard (against evil) or that it may produce a reminder for them.
The Holy Quran 26:193,194,195 and 200
193. The Faithful Spirit has descended with it.
194. Upon your heart that you may be of the warners.
195. In plain Arabic language.
200. Thus have we made it enter into the hearts of the guilty.
The Holy Quran 39:28,
An Arabic Quran without any crookedness, that they may guard (against evil).
The Holy Quran 41:3,
A Book of which the verses are made plain, an Arabic Quran for a people who know.
The Holy Quran 42:7,
And thus have We revealed to you an Arabic Quran, that you may warn the mother city and those around it, and that you may give warning of the day of gathering together wherein is no doubt; a party shall be in the garden and (another) party in the burning fire.
The Holy Quran 46:12,
And before it, the Book of Musa was a guide and a mercy: and this is a Book verifying (it) in the Arabic language that it may warn those who are unjust and as good news for the doers of good.
As we see from the ten verses above, Allah has a specific message that he wants to imprint on our minds and hearts by the adjectives which he brings with the word Arabic in the same verses. However, let us not rely on our own assumptions or interpretations as I can already hear the arguments that may arise that, yes, it may be that it was revealed in Arabic because the people of the time were Arabs and how could they understand another language but today we come from many different nations and tongues. So let us continue by looking at a clear hadith from Imam Jafar as-Sadiq (as).
Imam Sadiq (as) said:
"Learn Arabic, which is the word of Allah, and Allah has spoken to His servants in that language (the meaning of the Qur'an), and speak your jaws in Arabic and pronounce the end of the words clearly". (Al-Khesal. Vol 2. P 258)
In this above tradition, we see that the words of Imam As-Sadiq (as) are not advising or recommending us towards an action or a behavior, rather the words are decisive - a command. What is our Imam telling?
He says: "Learn Arabic", these are final and conclusive words from the sixth Imam (as). He further tells us that Arabic is the word of Allah, he does not say the Quran is the word of Allah but Arabic itself. He tells us that Allah has spoken to His servants in Arabic "That language" and finally, he explains the physical aspect of the recitation - how we should recite in Arabic? "Speak your jaws in Arabic and pronounce the end of the words clearly."
The above tradition coming from the Sixth Imam himself should also instill into our hearts that there is a science to the recitation of the Arabic Quran and when something has a science, then there is a cause and an effect. By mentioning the jaws, we see that there is some physical benefit for our actual body that comes from reciting the Holy Qur'an in Arabic but what more does he tell us about this recitation?
The following tradition, answers this question.
Imam Jafar As-Sadiq (as) said "Try your best to read the Qur'an correctly in true Arabic pronunciation in the same way that Arabs read it."
p 270 The life of Imam Al-Sadiq (as) Allama Baqir Sharif al Qarashi.
By the mentioned verses of the Holy Quran and the clear tradition (without even touching on the benefits of Arabic), there should be no doubt left about the actual command from our Imams and the guidance in the words of Allah himself that although we must understand the Holy Quran (reading in our native tongue), still there is nothing that can replace the function and role of the word of Allah in His own language.
“Muhammad is not the father of any man among you, but he is the Apostle of Allah and the Seal of the Prophets, and Allah has knowledge of all things” (33:40).
Based on some Islamic narrations, God has sent as many as 124000 prophets to humankind throughout history in different lands; the first of whom was Prophet Adam (AS), and the last divine prophet was Prophet Muhammad (PBUH).
What do you think was the primary purpose for which the prophets were raised? God says in the Holy Quran:
“O Prophet! Indeed, We have sent you as a witness, as a bearer of good news and as a warner. and as a summoner to Allah by His permission, and as a radiant lamp” (33:45-46)
“Certainly We sent Our apostles with manifest proofs, and We sent down with them the Book and the Balance, so that mankind may maintain justice;” (57:25)
According to the verses above and many other verses in the Quran [i], prophets were all sent to awaken the inner prophet within each person (i.e. people’s reason), guide them to the right path and invite them to monotheism (worshipping the only One God), which would ultimately lead to their well-being and salvation here in this world and also the hereafter. In fact, no one can deny the effective role prophets had in different aspects of people’s lives in history, as Will Durant puts:
“There is no significant example in history, before our time, of a society successfully maintaining moral life without the aid of religion. France, the United States, and some other nations have divorced their governments from all churches, but they have had the help of religion in keeping social order” .
Now you might wonder, “if God is One and all the prophets were sent to bring us closer to Him, then why would He send different religions?”
From the Quranic point of view there is No such thing as different religions, but rather “all Prophets irrespective of the fact whether they had or did not have an independent code of law, had the same mission and preached the same message” . Quran says:
“Indeed, with Allah religion is Islam, and those who were given the Book did not differ except after knowledge had come to them…” (3:19)
So, why would God send as many as 124000 prophets?
The answer is God’s message had to be renewed and developed according to the requirements of the time, the environment and also the people to whom God’s prophets were sent. Based on the stage of human development in each time and environment, a preaching or law-giving prophet [ii] would come to restore the divine message which had previously been changed, destroyed or distorted by people.
As stated above, people’s intellectual immaturity was the main reason why God renewed his message and developed it over time. However, by the advent of Islam and revelation of the holy Quran, humanity had passed the period of its childhood and had become mature enough to preserve its intellectual heritage, i.e., the religion of God. One thing that proves human’s maturity at the time of Prophet Muhammad (PBUH&HP) is that literacy had become more common among people.
That is why the Prophet’s (PBUH&HP) main miracle is not of anything physical, material and time-dependent, instead, it is a book which is made of words understandable for people of all times. In other words, God, then, guides people and shows them His signs using words (Quran) not by events like parting the sea (led by prophet Moses) or healing the blind or the sick (led by prophet Jesus). God’s message, accordingly, was revived through the revelation of the holy Quran and hence, Muhammad (PBUH&HP) was the last prophet of God.
It is noteworthy that the majority of divine prophets were the preaching ones who would interpret and spread the teachings of the law-giving prophets. But now that God has provided all requirements for humans to achieve their individual and social perfection giving them His book of guidance and wisdom to think, and people have reached a higher intellectual stage and become mature enough to interpret God’s message [iii], there won’t be a need for a new prophet.
At this age of knowledge, the religious scholars are capable of applying the general principles of Islam to the requirements of the time and place and deducing the rules of religious laws :
“The scholars are the inheritor of prophets” Imam Sadiq .
It is clear from what has been discussed above that the intellectual maturity of human has played an essential role in the finality of prophethood in several ways:
It has enabled man to receive his evolutionary program all at once and not by stages,
It has enabled him to keep the celestial Word of God (Quran) unaltered,
It has enabled him to interpret the revealed word of Allah, preach and propagate the teachings of religion and apply the religious principles to all the changing circumstances .
The last mentioned task is now performed by religious experts (Mujtahid) and is named Ijtihad meaning striving and making an effort to deduce the divine laws of Islam from the reliable sources and proofs.
The finality of prophethood does not mean that humanity is now able to dispense with religion. It is the need for prophets and the revelation of God that has ceased to exist, which is only because God’s message has been immune to any sort of alteration or distortion since the advent of Islam:
“Indeed We have sent down the Reminder, and indeed We will preserve it” (15:9)
This message is indestructible, and all people of next generations can have a recurring experience when dealing with it, irrespective of time.
However, God has never left the earth devoid of His guidance, and Imams as the successors of the Holy Prophet (PBUH&HP) have played the main part in maintaining humans’ spiritual connection with God from then on.
[i] “Certainly We raised an apostle in every nation [to preach:] ‘Worship Allah, and shun fake deities.’ Among them were some whom Allah guided, and among them were some who deserved to be in error. So travel over the land and observe how was the fate of the deniers” (16:36). Also see: (7:59, 7:65, 7:85 and 7:73)
[ii] The messengers of God where either law-giving, who would be sent with a noble message and guidance and whose number did not exceed the fingers of one hand, or preaching who would spread and propagate the teachings of the law-giving ones.
[iii] "We ought to present you with the principles and you ought to arrive at specific conclusions from them." Imam Sadiq (AS)

As other axioms, the afterlife (Ma’ad) is one of the first requisites for stepping into the religion of Islam and is defined as the existence of another world that creatures enter after their death, where they experience eternal life. It is noteworthy that the belief in receiving revelation and prophethood (Nubuwwah) builds the foundation of this axiom; in other words, one cannot find acceptance in the afterlife unless he comes to faith in prophethood and more importantly, monotheism (Tawhid).
Nevertheless, prophets didn’t come to impose the idea of Ma’ad on their followers, rather led people’s mind to ponder on this issue and recognize its validity. The reason for this concept to be considered as an axiom is that Islam not only wants us to have faith in the afterlife dependent on the belief in prophethood but also through individual and conscious investigation.
Aside from revelations that prophets received, there are some other ways and proofs for coming to believe in the afterlife which is the result of the intellectual and scientific efforts of human beings, including the knowledge of God, the universe, and human soul. Here we will briefly introduce each of these ways.
This argument which is based on the axiom of monotheism (Tawhid) -God exists and is the only one and should be accepted through rational thinking -, claims that God cannot be considered perfect and wise unless we believe in the existence of a world beyond this material world, an afterlife. In other words, without afterlife, the whole creation will become meaningless and vain.
If we find a wisdom governing the universe, then it necessitates the existence of another world which complements creation and forms a part of it. But why? We justify this issue based on God’s attributes.
God is just and has built the foundation of the universe, heaven, and earth on Justice. Human’s life, also, is placed within this just order; therefore, God’s justice requires every creature to be endowed with what they deserve in order to avoid denying their right.
The reward of many good deeds is not obtained in this world, just as many sins that cannot be punished thoroughly during this earthly life. Accordingly, since this world is limited and does not have the capacity to provide human beings with their deserved rewards or punishments, another world with infinite and unlimited time must exist in order to make up for the rights that people have not acquired in this world.
Wisdom is attributed to one whose deeds are always purposeful and would result in a specific and clear goal. Therefore, the wise God does not commit any absurd or nonsensical deed, otherwise, his action would be the result of his ignorance and lack of knowledge.
Moreover, the creation will not be meaningless, if it leads to eternity; if the creatures have been created for eternity and permanent endowment from God, then it shows an existence – as opposed to nothingness, inexistence – and continuity, thus it would not be absurd.
In addition, he has created every creature for a special purpose and has provided them with the means of reaching it. If He has endowed them with certain desires and capacities, then surely He has anticipated the appropriate answer for them, too.
For instance, in response to the urge for thirst or hunger in animals, He has created water and food in order to satisfy this need of them. Similarly, He has bestowed upon human beings the desire for immortality and eternal perfections; most of us feel the urge for eternity and unending life, as well as everything good in its best way.
If there were no way of reaching these desires, then why would God have placed them in human beings? These feelings do not fit into this earthly life and cannot be satisfied here; our All-wise God has for sure devised a plan for mankind to fulfill these needs, that is creating a world where they are able to experience everlasting life and achieve what they long for in their perfect forms.
Looking around, we can find many instances that remind us of the Resurrection and the revival of human beings in the afterlife. The very first thing that comes to mind when we think about the creation of the universe, is that the same power and wisdom that has created this world also has the power and ability to create another one. When we compare this power to our own capabilities, the occurrence of the afterlife seems far-fetched, however by the omnipotent being who has brought this world into life, this act is not at all infeasible.
Moreover, we are faced with many incidents in this world, on a daily basis, which is fairly similar to what will happen in the afterlife; we have seen them so many times that we have got used to their happening and consider them typical and insignificant, however at a closer look, we can find out the systematic and repeated order that governs the universe.
We constantly experience the cycle of life and death in nature with the change of seasons, that with the coming of winter and autumn everything - trees, flowers, etc. - on earth seems to be dying, and by spring, the sky sends its drops of rain to awake the hibernating earth and bestows a new breath on it.
Considering God’s power, the afterlife thus is neither impossible to happen nor something beyond our understanding or illogical based on the events that take place in the universe.
What we as human beings consider as our “self” or “I” is in fact a fixed and permanent fact. This “I” is actually the soul in mankind which is an immaterial and unchanging reality and has every action of the body under its control.
The axiom of the afterlife cannot be accepted unless one has a belief in the existence of a soul in human beings independent of their body, which is responsible for their conscious choices and deliberate actions. Otherwise, the belief in the afterlife is not possible, since if we see human beings as only this body that would be destroyed and diminished by death, then we cannot expect them to be revived exactly as the same; the human being that will be brought to life again would be for sure a different creature.
The only valid assumption would be that when a person dies his soul continues to exist until it returns to the body. Accordingly, the issue of the afterlife is justifiable through the knowledge of the human being’s reality which leads us to consider him as an immortal and infinite being.
Furthermore, as it was mentioned above, human beings are endowed with certain capacities - desire for immortality, to have eternal perfections - which are not fully compatible with the characteristics of this world and require another world for their fulfillment. If there were no resurrection for human beings, then his creation would be pointless from the very beginning, since his perfection has not manifested itself in this world and the means of receiving this goal would become useless and in vain.
To conclude, the aim of creation is going back toward God and to attend His final judgment among His creatures on Resurrection Day; everything in this world has been created to return to its God, reach eternity and never fail to exist.
They have come to life in order to pursue the path to their perfection and ultimately join God Almighty. It is noteworthy that the afterlife is not considered as dependent and the result of this world, but rather as a necessity and introductory for this earthly life; God has created this Universe, especially human beings with their extraordinary capacities - the power of the mind, the urge for seeking God and joining Him, etc.-, for becoming immortal in the afterlife and reaching the summit of their capabilities and eternal bliss; thus this world only provides the ground for the ultimate goal of creation. Afterlife is the final destination of creation and this world is only a temporary dwelling.
