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 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 do not grieve at their speech (O dear Prophet Mohammed – peace and blessings be upon him); indeed all honour is for Allah and He is the All Hearing, the 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 It is He who made the night for you to rest, and made the day enlightening. Indeed there are signs in this for those 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, "Indeed, those who invent falsehood about Allah will not succeed." 69 A brief enjoyment in this world! - and then unto Us will be their return, then We shall make them taste the severest torment because they used to disbelieve [in Allah, belie His Messengers, deny and challenge His Ayat (proofs, signs, verses, etc.)]. 70
