In whatever activity you may be engaged, and whichever part of the Quran you recite, and whatever deed you do, We are witness to it when you are engaged in it. Not the smallest particle on the earth or in heaven is hidden from your Lord; and there is nothing smaller or bigger but is recorded in a clear Book. 61 Now surely the friends of Allah-- they shall have no fear nor shall they grieve. 62 the ones who believe and are God-fearing. 63 Theirs 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. 64 And be not grieved by the sayings of those [who deny the truth]. Behold, all might and glory belong to God alone: He alone is all-hearing, all-knowing. 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 Tell them (O Muhammad!): 'Indeed those who invent lies against Allah will never prosper. 69 Let them profit by the world (while they may): In the end they will come back to Us. Then We shall make them taste severe punishment for having denied (the truth). 70
