And whosoever blindeth himself to the admonition of the Compassionate, We assign unto him a satan, and he becometh his companion. 36 And lo! they surely turn them from the way of Allah, and yet they deem that they are rightly 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 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 And if We take thee away, We shall surely take vengeance on them. 41 or make you see the end that We had promised them, for We have full power over them. 42 So hold fast to all that has been revealed to thee: for, behold, thou art on a straight way; 43 And verily, this (the Quran) is indeed a Reminder for you (O Muhammad SAW) and your people (Quraish people, or your followers), and you will be questioned (about it). 44 And question thou our messengers whom We sent before thee; did We appoint any deities other than (Allah) Most Gracious, to be worshipped? 45
