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 Repel not those who call upon their Lord at morn and evening, seeking His Countenance. Thou art not accountable for them in aught, nor are they accountable for thee in aught, that thou shouldst repel them and be of the wrong-doers. 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 humbly in your presence, say to them, “Peace be upon you – your Lord has prescribed mercy for Himself by His grace – that whoever among you commits a sin by folly and thereafter repents and reforms (himself), then indeed Allah is Oft Forgiving, Most Merciful.” 54 And Thus We expound revelations so that the way of the culprits may be shown up. 55
