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 Do not send away those who call upon their Lord in the morning and in the evening, seeking only His grace. You are not by any means accountable for them, nor are they accountable for you. If you turn them away, you yourself will become one of the unjust. 52 And thus do We try some of them by others so that they say: Are these they upon whom Allah has conferred benefit from among us? Does not Allah best know the grateful? 53 And when those who believe in Our signs come unto them, say thou: peace be on you; your Lord hath prescribed mercy for Himself; so that whosoever of you doeth an evil through ignorance, then repenteth thereafter and amendeth, then verily He is Forgiving, Merciful. 54 Thus do We explain Our revelations so that the sinful way can be plainly discerned. 55
