(Nothing of our revelation (even a single verse) do we abrogate or cause be forgotten, but we bring (in place) one better or the like thereof) [2:106].
The commentators of the Qur’an said: “The idolaters said: ‘Do you not see that Muhammad commands his Companions with something and then forbids them from the same and commands them to the exact opposite. One day he says something and the following day he retracts it. This Qur’an is nothing but the speech of Muhammad who has invented it. It is a speech that contradicts itself’. Allah, exalted is He, therefore revealed this verse (And when We put a revelation in place of (another)…) [16:101] and also (Nothing of our revelation (even a single verse) do we abrogate or cause be forgotten, but we bring (in place) one better or the like thereof…)”.
