Surah 10:64
"for them (there is) good news in this present life and in the Hereafter. No one can change the words of God. That is the great triumph!"
10.64 – No one can change the words of God
This verse states that there is no change in the words of Allah. The context seems to be an encouragement to the messenger in the midst of resistance to his message. The statement that Allah’s words are unchangeable repeats in slightly different forms at 6.34; 6.116; and 18.27.
