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 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 revelations come unto thee, say: Peace be unto you! Your Lord hath prescribed for Himself mercy, that whoso of you doeth evil through ignorance and repenteth afterward thereof and doeth right, (for him) lo! He is Forgiving, Merciful. 54 Thus We make plain Our signs, so that the path of the evil-doers might be laid bare. 55
