﴿ ۞ مَا نَنسَخْ مِنْ ءَايَةٍ أَوْ نُنسِهَا نَأْتِ بِخَيْرٍۢ مِّنْهَآ أَوْ مِثْلِهَآ ۗ أَلَمْ تَعْلَمْ أَنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌ ﴾

“Any message which, We annul or consign to oblivion We replace with a better or a similar one. Dost thou not know that God has the power to will anything?”

Then Allah mentions what was abrogated of the Qur'an and that which was not abrogated, as a direct reference to the claim of the Quraysh who said to the Prophet: O Muhammad! Why do you command us to do something and then forbid it, saying: (Such of Our revelations as We abrogate) We do not erase a verse that was acted upon before and which is now not acted upon (or cause to be forgotten) or leave unabrogated so that it is acted upon, (We bring one better) We send Gabriel with that which more profitable and easier to act upon (or the like) in reward, benefit and action. (Knowest thou not) O Muhammad (that Allah is Able to do all things?) of the abrogated and unabrogated.
