And warn therewith those who fear they shall be mustered to their Lord; they have, apart from God, no protector and no intercessor; haply they will be godfearing. 51 Do not drive away those who call on their Lord morning and evening, seeking only His Face. Nothing of their account falls upon you, and nothing of your account falls upon them, that you should drive them away and so become one of the harmdoers. 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
