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 Behold! verily on the friends of Allah there is no fear, nor shall they grieve; 62 Those who believe and (constantly) guard against evil;- 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 let not their speech grieve thee (O Muhammad). Lo! power belongeth wholly to Allah. He is the Hearer, the Knower. 65 Remember, whosoever is in the heavens and the earth belongs to God. Those who call on others they associate with God, follow nothing but conjecture, and only guess. 66 He it is who has made the night for your rest and the day to see. Surely, in this there are signs for people who listen. 67 They have said, "Allah has taken a son." Exalted is He; He is the [one] Free of need. To Him belongs whatever is in the heavens and whatever is in the earth. You have no authority for this [claim]. Do you say about Allah that which you do not know? 68 Say, “Indeed those who fabricate lies against Allah will never succeed.” 69 This world's portion (will be theirs), then unto Us is their return. Then We make them taste a dreadful doom because they used to disbelieve. 70
