No changing is there in the words of Allah. That! it is the mighty achievement. 64 And let not their saying grieve thee. Verily honour is Allah's wholly. He is the Hearer, the Knower. 65 Attention: Indeed to Allah belongs everyone that is in the heavens and in the earth.

He is All-sufficient; to Him belongs all that is in the heavens and in the earth; you have no authority for this. What, do you say concerning God that you know not? 68 Say: 'Those who forge against God falsehood shall not prosper. 69 [A brief] enjoyment in this world - and thereafter unto Us they must return: and then We shall let them taste suffering severe as an outcome of their persistent denial of the truth. 70
