Shiavault - a Vault of Shia Islamic Books The Collection and Preservation of the Qur'an The Claim that Tahrif was caused by the Caliphs Some hold that the interpolation, alteration, omission may have occurred after the death of the Prophet (‘s), perpetrated by the first two Caliphs or by Uthman when he came to power, or by someone of the later period. All these claims are invalid. If abu Bakr or Umar did it, then there can be two assumptions.
They either did it unintentionally, because, as it is believed, the Qur’an was not available in its entirety as it had not yet been compiled. Or they did it intentionally. In any case, the verses in which they interfered by way of Tahrif would be those concerning their leadership or even others. In all, there are three considerations: First, to say that they had no access to the whole of the Qur’an is totally out of question.
The Prophet (‘s) had taken great pains to see that it was committed to memory, and was constantly recited, slowly and elegantly, and the companions had compiled during the Prophet's time and after his passing away. This makes us certain that the Qur’an was with them, well guarded, all in one place or at various places, in the hearts of people or noted down on the papers. They were the people who had proudly preserved the poems and speeches of the pre-Islamic era.
How could they be expected to ignore the great Book whose laws they proclaimed, for which they had staked their lives, left their homes, spent their wealth, abandoned their families and children, and had taken a firm stand in the brilliant history of Islam. Can a reasonable person believe that they would be so indifferent so as to cause any loss of the Qur’an? A loss which could not be retrieved without the evidence of two witnesses?
Is it not tantamount to believing that there has been an addition or an omission in the Qur’an which was revealed to the Prophet (‘s)? Then there is the famous and widely acknowledged tradition of thaqalayn which invalidates all presumption, about Tahrif. The Prophet (‘s) said: 'I leave behind me two invaluable things: the Book of Allah and my Ahl ul-Bayt'.
This statement becomes meaningless if it is believed that the Qur’an had been lost during his time, because that which was lost would definitely be parts of the Book. In fact, this tradition points to the collection of the Qur’an during the Prophet's era; because scattered or memorised literature cannot be termed a book.
