(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 Surely God's friends -- no fear shall be on them, neither shall they sorrow. 62 Those who have accepted faith and practice piety. 63 for them is good tidings in the present life and in the world to come. There is no changing the words of God; that is the mighty triumph. 64 And be not grieved by the sayings of those [who deny the truth]. Behold, all might and glory belong to God alone: He alone is all-hearing, all-knowing. 65 Attention: Indeed to Allah belongs everyone that is in the heavens and in the earth. Those who call upon associates, other than Allah, follow nothing but assumptions, (they are) only lying. 66 It is God who has made the night for you to rest and has filled the day with light (as a means of visibility). In this there is evidence (of the existence of God) for the people who hear. 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 forge a lie against Allah shall not be successful. 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
