Warn by it those who fear to be gathered before their Lord, when they have no guardian or intercessor besides God, so that they may become God-fearing. 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 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 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 Thus do We explain Our revelations so that the sinful way can be plainly discerned. 55
