And warn with it those who fear to be brought before their Lord that they have no guardian or intercessor, other than Allah, in order that they are cautious. 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 Thus do We try men through one another so that they may ask: "Are these the ones of all of us who have been favoured by God?" Does God not know who are the grateful? 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 Thus do We explain Our revelations so that the sinful way can be plainly discerned. 55
