And whoever is averse to the Remembrance of the Most Gracious, We appoint a devil upon him, who stays with him. 36 And indeed those devils prevent them from the Straight Path, and they think they are on guidance! 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 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 Even if We take thee away, We shall be sure to exact retribution from them, 41 or We show thee a part of that We promised them, surely We have power over them. 42 Therefore, hold fast to that which is revealed to you, indeed, you are on the Straight Path. 43 And most surely it is a reminder for you and your people, and you shall soon be questioned. 44 And ask those We sent before you of Our messengers; have We made besides the Most Merciful deities to be worshipped? 45
