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 Behold! verily on the friends of Allah there is no fear, nor shall they grieve; 62 For those who believe and are mindful of God, 63 there is for them glad tidings in this present life and in the Everlasting Life. The Word of Allah is unchanging, that is the mighty triumph. 64 Do not let their speech grieve you. All might belongs to Allah. He is the Hearing, the Knowing. 65 No doubt! Verily, to Allah belongs whosoever is in the heavens and whosoever is in the earth. And those who worship and invoke others besides Allah, in fact they follow not the (Allah's so-called) partners, they follow only a conjecture and they only invent lies. 66 He it is who has made the night for your rest and the day to see. Surely, in this there are signs for people who listen. 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 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
