And thou (Muhammad) art not occupied with any business and thou recitest not a Lecture from this (Scripture), and ye (mankind) perform no act, but We are Witness of you when ye are engaged therein. And not an atom's weight in the earth or in the sky escapeth your Lord, nor what is less than that or greater than that, but it is (written) in a clear Book. 61 Now surely the friends of Allah-- they shall have no fear nor shall they grieve. 62 Those who have accepted faith and practice piety. 63 For them are glad tidings in this world and in the Hereafter. The words of Allah shall not change. That is the supreme triumph. 64 And let not their speech grieve thee (O Muhammad). Lo! power belongeth wholly to Allah. He is the Hearer, the Knower. 65 Verily whoever dwells in the heavens or the earth belongs to Allah. Those who invoke others beside Allah, associating them with Him in His divinity, only follow conjectures and are merely guessing. 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: Allah has taken a son (to Himself)! Glory be to Him: He is the Self-sufficient: His is what is in the heavens and what is in the earth; you have no authority for this; do you say against Allah what you do not know? 68 Say: "Those who fabricate lies about God will never 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
