The Quran and the Problem of Abrogation

http://www.answeringmuslims.com
According to the Qur’an, no one can change Allah’s words (6:115; 18:27). Yet Allah himself frequently changes his revelations by sending a verse that abrogates (or cancels) an earlier verse (2:106; 16:101). Since the Qur’an is supposedly eternal, our Muslim friends have a problem. From all eternity, the Qur’an contained (a) verses that contradict the commands of other verses, and (b) a verse claiming that, if the Qur’an were from anyone other than Allah, it would contain “much discrepancy” (4:82). Because the eternal Qur’an does contain much discrepancy (numerous contradictory commands), it cannot be the word of Allah, according to 4:82.
