To have iman in Allah’s books is to believe that Allah (Exalted be He) revealed heavenly books to His messengers in order to convey them to humankind.
These books contain nothing but the truth; they do not contain any falsehood. In them is the message of the Oneness of Allah (tawheed): that there is no creator, administrator, or owner except Him, that all worship should be directed to Him and none else, and that to Him belong all excellent Names and Attributes. He is nothing like His creation, and none can be compared to Him. Allah says:
Indeed We have sent Our Messengers with clear proofs, and revealed with them the Scripture and the Balance (justice) that mankind may keep up justice. (Al-Hadid 57:25)
Some of those books are the following:
1- The Scriptures of Ibrahim (Abraham, peace be upon him) and Musa (Moses, peace be upon him): The Qur’an has given a brief insight about the religious basic principles found in these scriptures. Allah says:
Or is he not informed with what is in the Scriptures of Musa? And of Ibrahim who fulfilled (or conveyed) all that (what Allah ordered him to do or convey)? That no burdened person (with sins) shall bear the burden (sins) of another. And that man can have nothing but what he [himself] strove for. And that his deeds will be seen (in the Hereafter). Then he will be recompensed with a full and the best recompense. (An-Najm 53:36-41)
2- The Tawrah: The Tawrah is the Sacred Book which was revealed to Musa. Allah says:
Verily, We did send down the Tawrah (to Musa), therein was guidance and light, by which the Prophets, who submitted themselves to Allah’s Will, judged the Jews. And the rabbis and the priests (too judged the Jews by the Tawrah after those Prophets) for to them was entrusted the protection of Allah’s Book, and they were witnesses thereto. Therefore fear not men but fear Me (O Jews) and sell not My Verses for a miserable price. And whosoever does not judge by what Allah has revealed, such are the disbelievers. (Al-Ma’idah 5:44)
3- The Zaboor: The Zaboor is the Book which was revealed to Dawud (David, peace be upon him). Allah says:
…and to Dawood We gave the Zaboor. (An-Nisaa’ 4:163)
4- The Injeel: The Injeel is the Sacred Book which was revealed to `Isa (Jesus, peace be upon him). Allah says:
And in their footsteps, We sent `Isa, son of Maryam (Mary), confirming the Tawrah that had come before him. And We gave him the Injeel, in which was guidance and light and confirmation of the Tawrah that had come before it, a guidance and an admonition for the Allah-fearing. (Al-Ma’idah 5:46)
A Muslim must believe in all the Heavenly Books. He must believe that they are from Allah, but he is required not act upon or follow them, for they were revealed for a specific time and people.
The Qur’an has explained some of the teachings which were found in the Tawrah and the Injeel. Allah says that from the things they mentioned was the prophecy of Muhammad (peace be upon him):
…and My Mercy embraces all things. That (Mercy) I shall ordain for those who are Allah-fearing, and give zakah; and those who believe in Our ayat; Those who follow the Messenger, the Prophet who can neither read nor write (Muhammad) whom they find written with them in the Tawrah and the Injeel, – he commands them all good things; and forbids them from of all kinds of evil; he allows them as lawful all good and lawful things, and prohibits them as unlawful all evil and unlawful things; and he releases them from their heavy burdens (of Allah’s Covenant), and from the fetters (bindings) that were upon them. (Al-A`raf 7:156)
5- The Qur’an: One must hold the following beliefs concerning it:
a- One must believe that the Qur’an is the exact and literal Speech of Allah which Jibreel (peace be upon him) brought to Muhammad in a clear Arabic language:
Which the trustworthy Rooh (Jibreel/Gabriel) has brought down; Upon your heart (O Muhammad that you may be (one) of the warners, In a plain Arabic language. (Ash-Shu`araa’ 26:193-195)
b- One must believe that the Qur’an is the last of the heavenly books, giving truth to the previous books in their message of the Tawheed of Allah and the obligation to worship and obey Him Alone. Allah abrogated all the previous books by the Qur’an. Allah says:
(It is) He Who has sent down the Book (the Qur’an) to you (Muhammad) with truth, confirming what came before it. And He sent down the Tawrah and the Injeel. Aforetime, as a guidance to mankind, And He sent down the Furqan (The Criterion) (of judgment between right and wrong; this Qur`an). (Aal `Imran 3:3-4)
c- One must believe that the Qur’an embodies all divine teachings. Allah says:
This day, I have perfected your religion for you, completed My favor upon you, and have chosen for you Islam as a religion. (Al-Ma’idah 5:3)
d- One must believe that it was revealed to all of humanity, and not to a specific nation or specific time period unlike the previous heavenly books. Allah says:
And We have not sent you (O Muhammad) except to all of humanity, as a giver of glad tidings and a warner, but most people know not. (Saba’ 34:28)
e) One must believe that Allah has protected the Qur`an from all types of distortion, whether addition, deletion, substitution or interpolation:
Remembrance (the Qur’an) and surely, it is We Who shall guard it (from distortion). (Al-Hijr 15:9)
The Fruits of Iman in Allah’s Books
Through the belief in Allah’s books, one benefits in the following ways:
1- One realizes the Mercy and Love Allah has for His slaves, in that He revealed to them books directing them to the path which leads to His Pleasure. He did not leave them to linger in confusion, leaving them for the Satan or their desires to snatch them away.
2- One realizes the Wisdom of Allah, in that He legislated for each specific nation what was suitable to their specific needs and conditions.
3- To distinguish the believers truthful in their faith from others, for it is incumbent upon one who believes in his own Book to believe in the other Heavenly Books which it prophesized.
4- As a multiplication of good deeds, for those who believe in their own Book and in addition to that believe in the Books of Allah which came after it will receive double reward. Allah says:
Those to whom We gave the Scripture (i.e. the Tawrah and the Injeel, etc.) before it, – they believe in it (the Qur’an). And when it is recited to them, they say: ‘We believe in it. Verily, it is the truth from our Lord. Indeed even before it we have been from those who submit themselves to Allah in Islam as Muslims.’ These will be given their reward twice over, because they are patient, and repel evil with good, and spend (in charity) out of what We have provided them. (Al-Qasas 28:52-54)
