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 Send not away those who call on their Lord morning and evening, seeking His face. In naught art thou accountable for them, and in naught are they accountable for thee, that thou shouldst turn them away, and thus be (one) of the unjust. 52 And even so do We try some of them by others, that they say: Are these they whom Allah favoureth among us? Is not Allah best Aware of the thanksgivers? 53 And when those who believe in Our revelations come unto thee, say: Peace be unto you! Your Lord hath prescribed for Himself mercy, that whoso of you doeth evil through ignorance and repenteth afterward thereof and doeth right, (for him) lo! He is Forgiving, Merciful. 54 Thus do We explain Our revelations so that the sinful way can be plainly discerned. 55
