Whoso blinds himself to the Remembrance of the All-merciful, to him We assign a Satan for comrade; 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, he says: O would that between me and you there were the distance of the East and the West; so evil is the associate! 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 Even if We take you away, We shall take vengeance upon them, 41 or show them to you suffering the torment with which We had threatened them. We are certainly dominant over them all. 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 And lo! it is in truth a Reminder for thee and for thy folk; and ye will be questioned. 44 Ask those of Our messengers whom We sent before you, "Did We ever appoint gods to be worshipped besides the Beneficent One?" 45
