Whoso blinds himself to the Remembrance of the All-merciful, to him We assign a Satan for comrade; 36 And indeed those devils prevent them from the Straight Path, and they think they are on guidance! 37 When he returns to us, he will say (to satan), "Would that there had been as long a distance between me and you as that between the East and West. What a terrible companion you have been". 38 But nothing will avail you on that day, for you were unjust, and you will be partners in the punishment. 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 Or (if) We show you that wherewith We threaten them, then verily, We have perfect command over them. 42 So hold fast to what has been revealed to you. Surely you are on the Straight Way. 43 The (Qur'an) is indeed the message, for thee and for thy people; and soon shall ye (all) be brought to account. 44 Ask those of Our Messengers We sent before thee: Have We appointed, apart from the All-merciful, gods to be served? 45
