And warn hereby those who fear lest they be gathered unto their Sustainer with none to protect them from Him or to intercede with Him, so that they might become [fully] conscious of Him. 51 Repel not those who call upon their Lord at morn and evening, seeking His Countenance. Thou art not accountable for them in aught, nor are they accountable for thee in aught, that thou shouldst repel them and be of the wrong-doers. 52 For it is in this way that We try men through one another - to the end that they might ask, "Has God, then, bestowed His favour upon those others in preference to us?" Does not God know best as to who is grateful [to Him]? 53 And when those who believe in Our signs come unto them, say thou: peace be on you; your Lord hath prescribed mercy for Himself; so that whosoever of you doeth an evil through ignorance, then repenteth thereafter and amendeth, then verily He is Forgiving, Merciful. 54 Thus We make plain Our signs, so that the path of the evil-doers might be laid bare. 55
