Give this warning to those in whose (hearts) is the fear that they will be brought (to judgment) before their Lord: except for Him they will have no protector nor intercessor: 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 through others that the disbelievers might say, "Is it these whom Allah has favored among us?" Is not Allah most knowing of those who are grateful? 53 And when those who believe in Our signs come to thee, say, 'Peace be upon you. Your Lord has prescribed for Himself mercy. Whosoever of you does evil in ignorance, and thereafter repents and makes amends, He is All-forgiving, All-compassionate.' 54 And Thus We expound revelations so that the way of the culprits may be shown up. 55
