In whatever business thou mayest be, and whatever portion thou mayest be reciting from the Qur'an,- and whatever deed ye (mankind) may be doing,- We are witnesses thereof when ye are deeply engrossed therein. Nor is hidden from thy Lord (so much as) the weight of an atom on the earth or in heaven. And not the least and not the greatest of these things but are recorded in a clear record. 61 Behold! verily on the friends of Allah there is no fear, nor shall they grieve; 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 (Muhammad), let not their words disappoint you; all dignity belongs to God. He is All-hearing and All-knowing. 65 Does not all that is in the heavens and the earth belong to God? (The unbelievers) who worship the idols instead of God follow only conjecture. What they preach are mere lies. 66 [whereas] it is He who has made the night for you, so that you might have rest therein, and the day, to make [you] see in this, behold, there are messages indeed for people who [are willing to] listen. 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 Say: "Verily, they who attribute their own lying inventions to God will never attain to a happy state!" 69 (They take their) enjoyment in this world, but to Us they shall return, then, We shall let them taste the terrible punishment because they were unbelievers. 70
