Thou art not engaged in any business, nor dost thou recite any part of the Qur'an, nor ye work any work, but We are witnesses over you when ye are engaged therein. And there escapeth not thy Lord the weight of an ant in the earth or the heavens, nor less than that nor greater, but it is in a Book luminous. 61 Lo! verily the friends of Allah are (those) on whom fear (cometh) not, nor do they grieve? 62 Those who believe and are cautious 63 For them there is the glad tiding [of happiness] in the life of this world and in the life to come; [and since] nothing could ever alter [the outcome of] God's promises, this, this is the triumph supreme! 64 And do not let their saying grieve thee; the glory belongs altogether to God; He is the All-hearing, the All-knowing. 65 Lo! is it not unto Allah that belongeth whosoever is in the heavens and whosoever is in the earth? Those who follow aught instead of Allah follow not (His) partners. They follow only a conjecture, and they do but guess. 66 It is He who has made the night dark for you so that you may rest in it, and the day a source of light. Surely, there are signs in this for a people who listen. 67 They say: "God has begotten a son." Immaculate is He and self-sufficient." Whatsoever is in the heavens and the earth belongs to Him. You have no proof for this (assertion): Why do you say things of God you do not know? 68 Say: "Verily, they who attribute their own lying inventions to God will never attain to a happy state!" 69 Some enjoyment in this world; then unto Us they shall return; then We shall let them taste the terrible chastisement, for that they were unbelievers. 70
