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 And drive not away those who call upon their Lord morning and evening, seeking His countenance. Not on thee is aught of their reckoning, nor on them aught of thine reckoning, so that thou mayest drive them away and thus become 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 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 do We make distinct the communications and so that the way of the guilty may become clear. 55
