And, [O Muhammad], you are not [engaged] in any matter or recite any of the Qur'an and you [people] do not do any deed except that We are witness over you when you are involved in it. And not absent from your Lord is any [part] of an atom's weight within the earth or within the heaven or [anything] smaller than that or greater but that it is in a clear register. 61 Behold! verily on the friends of Allah there is no fear, nor shall they grieve; 62 Those who believe, and are godfearing -- 63 for them is good tidings in the present life and in the world to come. There is no changing the words of God; that is the mighty triumph. 64 And let not their saying grieve thee. Verily honour is Allah's wholly. He is the Hearer, the Knower. 65 Surely, all who are in the heavens and on the earth belong to Him. What do those follow, who appeal to associates instead of to God? They merely follow conjecture and they are only guessing. 66 It is God who has made the night for you to rest and has filled the day with light (as a means of visibility). In this there is evidence (of the existence of God) for the people who hear. 67 They say, "God has begotten a son." Glory be to Him. He is the Self-Sufficient One; everything in the heavens and on the earth belongs to Him. Do you have any authority for this? Would you ascribe to God something which you do not know? 68 Say: 'Those who forge against God falsehood shall not prosper. 69 They may consider it a means of enjoyment in this life but (on the Day of Judgment) they will all return to Us. Then they will suffer for their disbelief the most severe punishment. 70
