Thou art not engaged in any business, nor dost thou recite any part of the Qur'an, nor ye work any work, but We are witnesses over you when ye are engaged therein. And there escapeth not thy Lord the weight of an ant in the earth or the heavens, nor less than that nor greater, but it is in a Book luminous. 61 Behold! verily on the friends of Allah there is no fear, nor shall they grieve; 62 Those who believe and keep their duty (to Allah). 63 Theirs are good tidings in the life of the world and in the Hereafter - There is no changing the Words of Allah - that is the Supreme Triumph. 64 And do not let their saying grieve thee; the glory belongs altogether to God; He is the All-hearing, the All-knowing. 65 Surely, all who are in the heavens and on the earth belong to Him. What do those follow, who appeal to associates instead of to God? They merely follow conjecture and they are only guessing. 66 It is He who has made the night dark for you so that you may rest in it, and the day a source of light. Surely, there are signs in this for a people who listen. 67 Some people have said that God has begotten a son. God is too Glorious to have a son! God is Self-sufficient and to Him belongs all that is in the heavens and the earth. In this, you (people) have no authority. Do you ascribe to God things of which you have no knowledge? 68 Say: "Those who fabricate lies about God will never succeed." 69 A little enjoyment in this world!- and then, to Us will be their return, then shall We make them taste the severest penalty for their blasphemies. 70
