And warn with it those who fear to be brought before their Lord that they have no guardian or intercessor, other than Allah, in order that they are cautious. 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 communications come to you, say: Peace be on you, your Lord has ordained mercy on Himself, (so) that if any one of you does evil in ignorance, then turns after that and acts aright, then He is Forgiving, Merciful. 54 And thus do We make distinct the communications and so that the way of the guilty may become clear. 55
