Warn by it those who fear to be gathered before their Lord, when they have no guardian or intercessor besides God, so that they may become God-fearing. 51 And turn not away those who invoke their Lord, morning and afternoon seeking His Face. You are accountable for them in nothing, and they are accountable for you in nothing, that you may turn them away, and thus become of the Zalimun (unjust). 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 Thus do We expound the revelations that the way of the unrighteous may be manifest. 55
