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."

Do I need to read the Holy Quran in Arabic or can I just read it in English?

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.
 

The plurality of different religions is undoubtedly one of the most important issues that concern people who are interested in religious studies today. Some of the questions they may ask include:

- Which religion is right?

- What do they have in common?

- How should the followers of different faiths behave when faced with the followers of other religions?

- Will all religions lead to eternal salvation?

In this article, we will see how Islam regards other religions and more specifically how it deals with the questions above.

All Divine faiths lead to the same God

According to the Islamic viewpoint, all Divine religions have been sent to connect human beings to their Gracious Creator, the only one God. Quran says:

“O People of the Book! Come to a common word between us and you: that we will worship no one but Allah, that we will not ascribe any partner to Him, and that some of us will not take some others as lords besides Allah…” (3:64)

As per this verse, Islam holds that all the other Divine religions root in Monotheism. The idea of God is actually so clear in these monotheistic faiths that some religious studies scholars regard it as an essential requirement for them to be included in the category of religions; in other words, those faiths that have no belief in God or practices of worship cannot be called religion at all.

Moreover, though the followers of some other faiths may worship different gods, all the Abrahamic religions assert the unity of God, and that He is the only Creator. This has been mentioned in the holy Quran many times:

“We did not send any apostle before you but that We revealed to him that ‘There is no god except Me; so worship Me.’” (21:25)

The belief in One God is somehow evident in the other religions as well; lots of them admit the fact that they feel there is some being which created the world and life and influences it to some extent. Quran says:

“If you ask them, ‘Who created the heavens and the earth, and who has disposed the sun and the moon?’ They will surely say, ‘Allah.’” (29:61)

This has also been asserted in the verses of Bible and Torah:

“I am the LORD your God, who brought you out of the land of Egypt, out of the house of slavery. "You shall have no other gods before Me. "You shall not make for yourself an idol, or any likeness of what is in heaven above or on the earth beneath or in the water under the earth.…” (Exodus 20:3) [1].

Islam Has Completed the Previous Religions

Contrary to popular belief, the religion of Islam does not deny the truth of the previous monotheistic religions, rather the religion of God was perfected in Islam through the revelation that was sent to the last messenger of God, Prophet Muhammad (PBUH):

“We have sent down to you the Book with the truth, confirming what was before it of the Book and as a guardian over it…” (5:48)

In fact, Islam has been revealed to purify the previous faiths from distortions and to complete their teachings:

“Today I have perfected your religion for you, and I have completed My blessing upon you, and I have approved Islam as your religion…” (5:3)

The advent of Prophet Muhammad (PBUH&HP) with his true religion was also predicted in the Bible:

“When the Spirit of truth comes, He will guide you into all truth. For He will not speak on His own, but He will speak what He hears, and He will declare to you what is to come” (John, 16:13) [2].

Muslims Respect the Followers of the Previous Monotheistic Faiths

Also, Islamic teachings and the holy Quran always emphasize the significance of respecting the freedom and other rights of the followers of the previous religions; Muslims, accordingly, hold the followers of those religions in high regard:

“Do not argue with the People of the Book [the followers of the previous monotheistic faiths] except in a manner which is best, except such of them as are wrongdoers, and say, ‘We believe in what has been sent down to us and in what has been sent down to you; our God and your God is one [and the same], and to Him do we submit.’” (29:46)

In Islam “There is no compulsion in religion” (2:256), and even if one chooses to follow another monotheistic faith other than Islam, he/she has every right to live in peace among Muslims as an honored citizen with all rights and privileges [3].

Islam Is a General Title for All the Prophets’ Call

“So set your heart as a person of pure faith on this religion, the original nature endowed by Allah according to which He originated mankind…” (30:30)

Muslims believe that the innate religion is something both Muslims and non-Muslims possess by birth; this original religion is what Muslims define as Islam. They also hold that the differences between various religions are due to particular requirements and potentials of societies during the various periods of prophecy:

“We did not send any apostle except with the language of his people so that he might make [Our messages] clear to them.” (14:4)

Consequently, the calls of the prophets were alike since all their invitations originated from a single source and followed a unified line of faith with a single aim, i.e., submission to the Lord of the worlds, which is the real meaning of Islam:

“Indeed, with Allah religion is Islam” (3:19)

In fact, Islam, i.e., submission to Allah is the cornerstone of all religions.

So, Muslims testify to the truth of all God’s Messengers and that they have all agreed with each other, each of them testifying to the truth of the words of the preceding Prophets (AS) and giving the tidings of the Divine appointment of the next Messenger:

“Say, ‘We have faith in Allah and what has been sent down to us, and what was sent down to Abraham, Ishmael, Isaac, Jacob and the Tribes, and that which Moses and Jesus were given, and that which the prophets were given by their Lord; we make no distinction between any of them and to Him do we submit’” (2:136).

Indeed, with Allah religion is Islam [4]

Islam is a religion for all human beings of all time:

 “We did not send you [Muhammad] but as a mercy to all the nations” (21:107)

This verse clearly indicates the universality of the message brought by Prophet Muhammad (PBUH&HP).

Although the holy Quran regards belief in the prophets a major basis of a Muslim’s ideology, it maintains that what was revealed to the last Prophet, Muhammad (PBUH&HP), was the most advanced program and the perfect law of the divine religion:

“It is He who has sent His Apostle with guidance and the true religion that He may make it prevail over all religions though the polytheists should be averse” (61:9).

Accordingly, it will not be accepted by Allah to remain on the previous incomplete paths after the revelation of the Holy Quran:

“Should anyone follow a religion other than Islam, it shall never be accepted from him, and he will be among the losers in the Hereafter” (3:85).

There Will Be No Fear for the True Followers of Other Faiths

The verse above does not, however, mean that the followers of other faiths will be all losers. Quite the opposite! There are believers who have not had a chance to reach the completed and updated truth, or those who are exposed to intense propaganda against Islam and think it is impossible that such a religion (distorted image of Islam) might be the right way to salvation, or even those Christians, Jews or any other believers who have searched enough and have been convinced, based on reasons, that their beliefs are right (even if their reasons seem invalid and wrong in the eyes of Muslims); what do you think Quran says about them?

“Indeed, the faithful, the Jews, the Christians and the Sabaeans—those of them who have faith in Allah and the Last Day and act righteously—they shall have their reward from their Lord, and they will have no fear, nor will they grieve” (2:62).

Finally, going through the Quranic verses about religions and their messages, we may conclude that Islam encompasses all the other divine revelations; the ones that have been distorted throughout history, or simply do not sufficiently meet people’s needs any longer; Islam is, in fact, the final, authentic, complete, and updated message of God that draws a perfect picture of man and the base for his reformation that will ultimately lead to his salvation.
