Unchangeable

No one can alter Allah’s words.

6:34Messengers indeed have been denied before thee, and they were patient under the denial and the persecution till Our succour reached them. There is none to alter the decisions of Allah. Already there hath reached thee (somewhat) of the tidings of the messengers (We sent before).

6:115Perfected is the Word of thy Lord in truth and justice. There is naught that can change His words. He is the Hearer, the Knower.

10:64Theirs are good tidings in the life of the world and in the Hereafter - There is no changing the Words of Allah - that is the Supreme Triumph.

18:27And recite that which hath been revealed unto thee of the Scripture of thy Lord. There is none who can change His words, and thou wilt find no refuge beside Him.
