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 Surely God's friends -- no fear shall be on them, neither shall they sorrow. 62 Those who believe and guarded (against evil): 63 There are good tidings for them in the life of this world and in the Hereafter; the Words of Allah cannot change; this is the supreme success. 64 And let not their speech grieve you; surely might is wholly Allah's; He is the Hearing, the Knowing. 65 Now, surely, whatever is in the heavens and whatever is in the earth is Allah's; and they do not (really) follow any associates, who call on others besides Allah; they do not follow (anything) but conjectures, and they only lie. 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, '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, "Those who invent falsehoods about God shall not prosper." 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
