There is no changing the words of God; that is the mighty triumph. 64 And let not their speech grieve you; surely might is wholly Allah's; He is the Hearing, the Knowing. 65 Verily whoever dwells in the heavens or the earth belongs to Allah.

He is self-sufficient! His are all things in the heavens and on earth! No warrant have ye for this! say ye about Allah what ye know not? 68 Tell them (O Muhammad!): 'Indeed those who invent lies against Allah will never prosper. 69 A brief enjoyment in this world! - and then unto Us will be their return, then We shall make them taste the severest torment because they used to disbelieve [in Allah, belie His Messengers, deny and challenge His Ayat (proofs, signs, verses, etc.)]. 70
