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 Lo! verily the friends of Allah! no fear shall come upon them nor shall they grieve. 62 Those who believe and keep their duty (to Allah). 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 Do not let their speech grieve you. All might belongs to Allah. 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 He it is Who has appointed for you the night that you may rest therein, and the day to make things visible (to you). Verily, in this are Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) for a people who listen (i.e. those who think deeply). 67 They said, “Allah has created a son for Himself”- Purity is to Him! He is the Perfect (Unwanting, free of needs); to Him only belongs all whatever is in the heavens and all whatever is in the earth; “You do not have any proof of this; do you say a thing concerning Allah which you do not know?” 68 Say: "Verily, those who invent lie against Allah will never be successful" 69 Their portion is short-lived enjoyment in this world; but to Us they shall return. Then We shall make them taste a severe punishment, because of their denial of truth. 70
