Abrogation in Quran

 Allah, may He be exalted, said (interpretation of the meaning):

“Whatever a Verse (revelation) do We abrogate or cause to be forgotten, We bring a better one or similar to it. Know you not that Allah is able to do all things?

Know you not that it is Allah to Whom belongs the dominion of the heavens and the earth? And besides Allah you have neither any Walee (protector or guardian) nor any helper.”

[al-Baqarah 2:106-107].

Naskh (abrogation) means moving; thus the meaning of abrogation is moving those who are accountable from one prescribed ruling to another, or waiving the ruling. The Jews used to condemn abrogation and claim that it was not permissible, even though it was referred to in the Torah; thus their rejection of it constituted disbelief and was based on pure whims and desires. 

Allah, may He be exalted, has told us of His wisdom in abrogation, and that whenever He abrogates any verse “or cause[s] [it] to be forgotten” i.e., causes people to forget it and removes it from their hearts

“We bring a better one” that is more beneficial for you

“or similar to it.”

This indicates that the abrogation will not be less beneficial to you than the original ruling, because Allah’s bounty always increases, especially for this ummah, for which He has made its religion very easy. 

And He tells us that whoever rejects abrogation has rejected His sovereignty and might, as He says: “Know you not that Allah is able to do all things? Know you not that it is Allah to Whom belongs the dominion of the heavens and the earth?”.
