(O Prophet!) Whatever you may be engaged in, whether you recite any portion of the Qur'an, or whatever else all of you are doing, We are witnesses to whatever you may be occupied with. Not even an atom's weight escapes your Lord on the earth or in the heaven, nor is there anything smaller or bigger than that, except that it is on record 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 keep their duty (to Allah). 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 Do not let their words grieve you. Surely, all might and glory belongs to God alone; He is the all-hearing, the all-knowing. 65 Indeed all those in the heavens and all those in the earth are in Allah’s control; and what do those who pray to the partners instead of Allah, follow? They do not follow anything except assumption, and they only make guesses. 66 It is He Who created the night for you so that you may gain rest in it and the day giving sight; indeed in this are signs for the people who heed. 67 They say, 'God has taken to Him a son. Glory be to Him! He is All-sufficient; to Him belongs all that is in the heavens and in the earth; you have no authority for this. What, do you say concerning God that you know not? 68 Tell them (O Muhammad!): 'Indeed those who invent lies against Allah will never prosper. 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
