To whosoever blinds himself from the Remembrance of the Merciful, We shall assign him a satan so he is his companion, 36 and they bar them from the way, and they think they are guided, 37 Until, when he comes to Us [at Judgement], he says [to his companion], "Oh, I wish there was between me and you the distance between the east and west - how wretched a companion." 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 Whether We take thee away, We shall take vengeance upon them, 41 Or show you some of what We have promised them. They are certainly well within Our power. 42 Therefore hold fast to that which has been revealed to you; surely you are on the right path. 43 The Quran is a reminder to you and to your people and you will soon be questioned about it. 44 And ask those of Our messengers whom We sent before thee: Did We ever appoint gods to be worshipped beside the Beneficent? 45
