And whoever is blinded from remembrance of the Most Merciful - We appoint for him a devil, and he is to him a companion. 36 And most surely they turn them away from the path, and they think that they are guided aright: 37 Until when he comes before Us he will say (to the devil): "Would to God there was a distance of the East and West between you and me, for you were an evil companion!" 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, (O Prophet), then make the deaf hear, or direct to the Right Way the blind or one lost in manifest error? 40 Whether We take thee away, We shall take vengeance upon them, 41 and whether We show thee [or do not show thee in this world] the fulfillment of what We have promised them - verily, 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 And most surely it is a reminder for you and your people, and you shall soon be questioned. 44 Ask those of Our messengers whom We sent before you, "Did We ever appoint gods to be worshipped besides the Beneficent One?" 45
