ABROGATION (NASKH) IN ISLAM

This is a difficult question to resolve, but obviously critical when one looks at the contradictions in the Quran.

Middle East Quarterly (2007). 

The Qur'an is unique among sacred scriptures in accepting a doctrine of abrogation in which later pronouncements of the Prophet declare null and void his earlier pronouncements.[9] Four verses in the Qu'ran acknowledge or justify abrogation:

• When we cancel a message, or throw it into oblivion, we replace it with one better or one similar. Do you not know that God has power over all things?[10]
• When we replace a message with another, and God knows best what he reveals, they say: You have made it up. Yet, most of them do not know.[11]
• God abrogates or confirms whatsoever he will, for he has with him the Book of the Books.[12]
• If we pleased, we could take away what we have revealed to you. Then you will not find anyone to plead for it with us.[13]
