If anyone withdraws himself from remembrance of (Allah) Most Gracious, We appoint for him an evil one, to be an intimate companion to him. 36 Devils divert men from the [right] way, while they think that they are rightly guided. 37 But in the end, when he [who has thus sinned] appears before us [on Judgment Day,] he will say [to his other self,] "Would that between me and thee there had been the distance of east and west!" for, evil indeed [has proved] that other self! 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 Then will you make the deaf hear, [O Muhammad], or guide the blind or he who is in clear error? 40 But if We should take you away, still We shall inflict retribution on 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 Therefore hold fast to that which has been revealed to you; surely you are on the right path. 43 And verily it is an admonition unto thee and thy people; and presently ye will be questioned. 44 Yet [above all else,] ask any of Our apostles whom We sent forth before thy time whether We have ever allowed that deities other than the Most Gracious be worshipped! 45
