Whoso blinds himself to the Remembrance of the All-merciful, to him We assign a Satan for comrade; 36 And verily, they (Satans / devils) hinder them from the Path (of Allah), but they think that they are guided aright! 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 Can you [Prophet] make the deaf hear? Or guide either the blind or those who are in manifest error? 40 We shall inflict retribution on them, whether We take you away from the world (before We do that), 41 and whether We show thee [or do not show thee in this world] the fulfillment of what We have promised them - verily, 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 It is a (source) of greatness for you and your people. You will surely be questioned about it. 44 And ask those We sent before you of Our messengers; have We made besides the Most Merciful deities to be worshipped? 45
