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 Satan will prevent them from the right path while they think that they have the right guidance. 37 Till, when (such a one) comes to Us, he says [to his Qarin (Satan / devil companion)] "Would that between me and you were the distance of the two easts (or the east and west)" a worst (type of) companion (indeed)! 38 It shall not profit you today, since you did evil, that you are partners in the chastisement. 39 Then will you make the deaf hear, [O Muhammad], or guide the blind or he who is in clear error? 40 So if We take you away, We shall then indeed take revenge from them. 41 Or show you what We have promised them – We therefore have complete control over them. 42 Therefore, hold fast to that which is revealed to you, indeed, you are on the Straight Path. 43 It is a (source) of greatness for you and your people. You will surely be questioned about it. 44 And ask them – did any of the Noble Messengers We sent before you, appoint any other Gods except the Most Gracious, whom they used to worship? 45
