And warn with it those who fear that they shall be gathered to their Lord-- there is no guardian for them, nor any intercessor besides Him-- that they may guard (against evil). 51 Hence, repulse not [any of] those who at morn and evening invoke their Sustainer, seeking His countenance. Thou art in no wise accountable for them - just as they are in no wise accountable for thee - and thou hast therefore no right to repulse them: for then thou wouldst be among the evildoers. 52 And thus We have tried some of them by means of others, that they might say: are those they whom God hath favoured amongst us? Is not Allah the Best Knower of the thankful? 53 When those come to thee who believe in Our signs, Say: "Peace be on you: Your Lord hath inscribed for Himself (the rule of) mercy: verily, if any of you did evil in ignorance, and thereafter repented, and amend (his conduct), lo! He is Oft-forgiving, Most Merciful. 54 And thus do We make distinct the communications and so that the way of the guilty may become clear. 55
