And whoever is blinded from remembrance of the Most Merciful - We appoint for him a devil, and he is to him a companion. 36 and they bar them from the way, and they think they are guided, 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 Canst thou (Muhammad) make the deaf to hear, or canst thou guide the blind or him who is in error manifest? 40 Whether We take thee 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 Therefore, hold fast to that which is revealed to you, indeed, you are on the Straight Path. 43 And most surely it is a reminder for you and your people, and you shall soon be questioned. 44 Ask Our Messengers whom We sent before you if We have ever made gods, other than the Merciful, to be worshipped. 45
