Warn those who fear, through this (Qur'an), that they will be gathered before their Lord, and they will have none to protect or intercede for them apart from Him. They may haply take heed for themselves. 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 In this way We try some of them by means of others, so that they may ask, "Are these [lowly ones] whom God has singled out for His favours from among us? Does God not know best who are the grateful ones?" 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 the signs in detail: that the way of the sinners may be shown up. 55
