Warn hereby those who fear (because they know) that they will be gathered unto their Lord, for whom there is no protecting ally nor intercessor beside Him, that they may ward off (evil). 51 Send not away those who call on their Lord morning and evening, seeking His face. In naught art thou accountable for them, and in naught are they accountable for thee, that thou shouldst turn them away, and thus be (one) of the 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 come to you who believe in Our verses, say, "Peace be upon you. Your Lord has decreed upon Himself mercy: that any of you who does wrong out of ignorance and then repents after that and corrects himself - indeed, He is Forgiving and Merciful." 54 And thus clearly do We spell out Our messages: and [We do it] so that the path of those who are lost in sin might be distinct [from that of the righteous]. 55
