He who is negligent to remember the Merciful One, to him We assign a satan as his boon companion, 36 whereupon, behold, these [evil impulses] bar all such from the path [of truth,] making them think that they are guided aright! 37 To the extent that when the disbeliever will be brought to Us, he will say to his devil, “Alas – if only there was the distance* of east and west, between you and me!” – so what an evil companion** he is! (* Had I not listened to you. **They will be bound together in chains.) 38 They will be told on the Day of Judgment, "Regret will never be of any benefit to you. You have done injustice to your souls and you will share the torment". 39 Can you [Prophet] make the deaf hear? Or guide either the blind or those who are in manifest error? 40 But if We should take you away, still We shall inflict retribution on them; 41 or make you see the end that We had promised them, for We have full power over them. 42 Hold thou fast wherefore to that which is revealed unto thee: verily thou art on the straight path. 43 It is a (source) of greatness for you and your people. You will surely be questioned about it. 44 Ask all Our Messengers whom We sent before you whether We had appointed any deities beside the Merciful One to be worshipped. 45
