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 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 Thus did We try some of them by comparison with others, that they should say: "Is it these then that Allah hath favoured from amongst us?" Doth not Allah know best those who are grateful? 53 When those who believe in Our revelations come to you, say to them: "Peace on you." Your Lord has prescribed grace for Himself, so that in case one of you commits evil out of ignorance, then feels repentant and reforms, He may be forgiving and kind. 54 Thus do We explain the signs in detail: that the way of the sinners may be shown up. 55
