(O Prophet!) Whatever you may be engaged in, whether you recite any portion of the Qur'an, or whatever else all of you are doing, We are witnesses to whatever you may be occupied with. Not even an atom's weight escapes your Lord on the earth or in the heaven, nor is there anything smaller or bigger than that, except that it is on record in a Clear Book. 61 Those who are close to God shall certainly have no fear, nor shall they grieve. 62 Those who believed (in the Oneness of Allah - Islamic Monotheism), and used to fear Allah much (by abstaining from evil deeds and sins and by doing righteous deeds). 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 do not let their saying grieve thee; the glory belongs altogether to God; He is the All-hearing, the All-knowing. 65 No doubt! Verily, to Allah belongs whosoever is in the heavens and whosoever is in the earth. And those who worship and invoke others besides Allah, in fact they follow not the (Allah's so-called) partners, they follow only a conjecture and they only invent lies. 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 say: 'Allah has taken a son' Exaltations be to Him (Allah)! Rich is He. To Him belongs all that is in the heavens and the earth you have no authority for this! What, do you say of Allah what you do not know? 68 Say: Verily those who invent a lie concerning Allah will not succeed. 69 [A brief] enjoyment in this world - and thereafter unto Us they must return: and then We shall let them taste suffering severe as an outcome of their persistent denial of the truth. 70
