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 Oh, surely the friends of Allah have nothing to fear, nor shall they grieve - 62 Those who believe, and are godfearing -- 63 Unto them is glad tidings in the life of the world and in the Hereafter. No changing is there in the words of Allah. That! it is the mighty achievement. 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 OH, VERILY, unto God belongs whoever is in the heavens and whoever is on earth: hence, what is it that they follow - those who invoke, beside God, beings to whom they ascribe a share in His divinity? They follow but the conjectures [of others,] and themselves do nothing but guess 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 begotten a son." Glory be to Him. He is the Self-Sufficient One; everything in the heavens and on the earth belongs to Him. Do you have any authority for this? Would you ascribe to God something which you do not know? 68 Say, “Indeed those who fabricate lies against Allah will never succeed.” 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
