But as for anyone who chooses to remain blind to the remembrance of the Most Gracious, to him We assign an [enduring] evil impulse, to become his other self: 36 And verily they hinder them from the way, whilst they deem that they are rightly guided. 37 At length, when (such a one) comes to Us, he says (to his evil companion): "Would that between me and thee were the distance of East and West!" Ah! evil is the companion (indeed)! 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 We shall revenge them either after your death 41 Or (if) We show you that wherewith We threaten them, then verily, We have perfect command over them. 42 Therefore hold fast to what We have divinely revealed to you; indeed you are upon the Straight Path. (The Holy Prophets can never go astray). 43 The Quran is a reminder to you and to your people and you will soon be questioned about it. 44 Ask those of Our Messengers We sent before thee: Have We appointed, apart from the All-merciful, gods to be served? 45
