He who is negligent to remember the Merciful One, to him We assign a satan as his boon companion, 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 Wherefore canst thou make the deaf to hear, or canst thou guide the blind or him who is is error manifest? 40 We shall revenge them either after your death 41 Or show you some of what We have promised them. They are certainly well within Our power. 42 So hold fast to what has been revealed to you. You are truly 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 Ask all Our Messengers whom We sent before you whether We had appointed any deities beside the Merciful One to be worshipped. 45
