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 When such a person comes to Us, he will say [to his comrade], "If only you had been as far away from me as east is from west. What an evil comrade!" 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 What! can you then make the deaf to hear or guide the blind and him who is in clear error? 40 Even if We take you away, We shall take vengeance upon them, 41 Or (if) We show you that wherewith We threaten them, then verily, We have perfect command over them. 42 So hold fast to what has been revealed to you. Surely you are on the Straight Way. 43 And lo! it is in truth a Reminder for thee and for thy folk; and ye will be questioned. 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
