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.
 

Death and the nature of afterlife, have always been mysterious to human beings. Everybody is willing to either find it out himself or to have faith in what has been said and discovered about it. Muslims seek the answer in the Quran, the holy book they believe in. In Quranic thoughts, death is nothing but the transfer of the human soul from the natural universe to the spiritual world, going back to the one who created it all, i.e., God; “Indeed we belong to Allah, and to Him do we indeed return” (2:156).

According to the Holy Quran, death is no inexistence or destruction, But a threshold to the next stage of life and existence. However, it is noteworthy that what forms the exact nature of humankind is not the physical and material composition that disintegrates and gets destroyed after death; in fact, our real self is made up of our soul that is seized and released from the captivity of the body and then returns to its origin, the Divine presence, God.

Therefore death in the Islamic viewpoint happens when the immortal soul or self of a human cuts its attachment and relationship from the body and consequently, the body perishes while the soul continues its life without it.

“Say: You will be taken away by the angel of death, who has been charged with you. Then you will be brought back to your Lord” (32:11).

Life after Death

Now one might wonder what happens to us after death; are we going to begin our lives in the hereafter right away, or we will experience a different temporary stage of life that lasts up until the Day of Judgment?

Muslims get the information about this issue, through revelations received by the last Prophet, Muhammad (PBUH), in verses of the Quran. Based on what has been revealed to our prophet, the afterlife does not begin right after we die. Human beings will enter an intermediate world called “Barzakh” in which they would feel, see and hear everything differently; there would be things they enjoy and ones they suffer from, based on their deeds in this earthly life. In short, man will go through two different stages of life after death; one temporary that is to come right after death, and one that lasts forever and will never end.

The Intermediate World (Barzakh)

“…And ahead of them is a barrier until the day they will be resurrected” (23:100).

Literally speaking, “Barzakh” is a barrier that stands between two things; Quran, however, introduces it as an interval between the death of a man and the forthcoming hereafter (Ma’ad); a stage at which human leads either a blissful or miserable life, based on his deeds on earth.

The Day of Judgment

The second stage of eternal life starts on the Day of Judgment (Yawm Al-Hisab). Unlike “Barzakh”, at which humans enter individually after death, this occurs to all the beings and the whole universe at the same time; every being starts a new permanent stage of life.

“And you will see the angels surrounding the Throne, celebrating the praise of their Lord, and judgment will be made between them with justice, and it will be said," All praise belongs to Allah, the Lord of all the worlds” (39:68).

Near the time of resurrection, all beings will cease to exist after hearing the first blow of the Horn (Israfil’s Horn). Then there will be a second blowing, and all Creation from the beginning till the end of time will be resurrected. People will be coming out of their graves in their physical bodies, standing and waiting, severely worried, under the sun to be judged by their Lord and to see rewards and retributions for their benevolent and malevolent actions in the earthly life.

“And when the Trumpet is blown, behold, there they will be, scrambling from their graves towards their Lord” (36:51).

Paradise and Hell

That day humans will be either granted admission to enter Paradise, where they will enjoy spiritual and physical pleasure, or sentenced to suffer spiritual and physical torment in Hell forever.

“[To the righteous it will be said], O soul at peace! Return to your Lord, pleased, pleasing! Then enter among My servants! And enter My paradise” (89:27-30).

“... and whoever disobeys Allah and His apostle, indeed there will be for him the fire of hell, to remain in it forever” (72:23).

The nature of Heaven and Hell has been analogously described in the Quran many times. However, there are verses that say:

“No one knows what has been kept hidden for them of comfort as a reward for what they used to do” (32:17).

Accordingly, What Heaven and Hell are really like is far beyond our comprehension and so cannot be explained to us unless they are allegorical.

The Relation between Earthly Life and Afterlife

In fact, the earthly affairs of mankind here are not separable from those of hereafter; that is the otherworldly destiny of a man is determined by himself in this world.  Many verses of the Quran indicate that the same good or bad deeds man commits in this life, will return to him, as their own reward or punishment, on the day of requital. People will live with the embodiment of their good or evil deeds, which are going to be their eternal companions.

The Similarities and Differences of Earthly Life and Afterlife

One of the common features of this earthly life and the hereafter is that they are both real and actual; in other words, human beings are aware of themselves and what belongs to them in both worlds. There are joy and pleasure, suffering and pain, or happiness and misery in both lives. In both worlds, human possesses a physical body and particular instincts. Nevertheless, there are basic differences too.

The reproduction, childhood, youth, senescence, and death we experience here will not exist in the hereafter. Here is the place of action while the hereafter is where we should pay for what we have done and compensate for our deeds. Life in this world is followed by death whereas we will lead an eternal life in the other world. Quran says:

“The life of this world is nothing but a diversion and play, but the abode of the Hereafter is indeed Life, had they known” (29:64).

Man’s perception will be heightened in the afterlife, and he will realize the truth of everything -every action or every being- more vividly. “[It will be said], You were certainly oblivious of this. We have removed your veil from you, and so your sight is acute today” (50:22).

In this earthly life, the man easily gets bored and tired of everything; he is always seeking what he does not have, and once he finds it he soon feels jaded and starts looking for something else. It seems as though he has lost something he can hardly find. In the hereafter, however, he will find what he has always longed for and what he has been attached to deep in his nature; that is Allah, the Lord of the universe.
