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 The friends of God will certainly have nothing to fear, nor will they be grieved. 62 Those who believe and keep their duty (to Allah). 63 They shall have good news in this world's life and in the hereafter; there is no changing the words of Allah; that 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 Why, surely to God belongs everyone that is in the heavens and in the earth; they follow, who call upon associates, apart from God -- they follow nothing but surmise, merely conjecturing. 66 [whereas] it is He who has made the night for you, so that you might have rest therein, and the day, to make [you] see in this, behold, there are messages indeed for people who [are willing to] listen. 67 They have said, "Allah has taken a son." Exalted is He; He is the [one] Free of need. To Him belongs whatever is in the heavens and whatever is in the earth. You have no authority for this [claim]. Do you say about Allah that which you do not know? 68 Say: Verily those who invent a lie concerning Allah will not 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
