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 Surely God's friends -- no fear shall be on them, neither shall they sorrow. 62 Those who believed (in the Oneness of Allah - Islamic Monotheism), and used to fear Allah much (by abstaining from evil deeds and sins and by doing righteous deeds). 63 For them are good tidings in the worldly life and in the Hereafter. No change is there in the words of Allah. That is what is the great attainment. 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 Allah alone Who has made the night that you may rest in it, and has made the day light-giving. Surely in that there are signs for those who give heed (to the call of the Messenger). 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: "Verily, those who invent lie against Allah will never be successful" 69 They may enjoy the life of this world, but in the end they must return to Us, and then We shall cause them to taste severe chastisement for their disbelieving.' 70
