And you are not (engaged) in any affair, nor do you recite concerning it any portion of the Quran, nor do you do any work but We are witnesses over you when you enter into it, and there does not lie concealed from your Lord the weight of an atom in the earth or in the heaven, nor any thing less than that nor greater, but it is in a clear book. 61 Surely God's friends -- no fear shall be on them, neither shall they sorrow. 62 Those who believe and are cautious 63 Unto them is glad tidings in the life of the world and in the Hereafter. No changing is there in the words of Allah. That! it is the mighty achievement. 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 Why, surely to God belongs everyone that is in the heavens and in the earth; they follow, who call upon associates, apart from God -- they follow nothing but surmise, merely conjecturing. 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 [And yet] they assert, "God has taken unto Himself a son!" Limitless is He in His glory! Self-sufficient is He: unto Him belongs all that is in the heavens and all that is on earth! No evidence whatever have you for this [assertion]! Would you ascribe unto God something which you cannot know? 68 Say, "Indeed, those who invent falsehood about Allah will not succeed." 69 They may enjoy the life of this world, but in the end they must return to Us, and then We shall cause them to taste severe chastisement for their disbelieving.' 70
