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 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 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 When those who believe in Our revelations come to you, say, "Peace be upon you. Your Lord has taken it upon Himself to be merciful. So that if any one among you does evil in ignorance and repents thereafter and makes amends, then He is most forgiving and ever merciful." 54 Thus do We explain Our revelations so that the sinful way can be plainly discerned. 55
