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 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 When those come to thee who believe in Our signs, Say: "Peace be on you: Your Lord hath inscribed for Himself (the rule of) mercy: verily, if any of you did evil in ignorance, and thereafter repented, and amend (his conduct), lo! He is Oft-forgiving, Most Merciful. 54 And this is how We explain Our verses clearly and so that the way of the criminals become well exposed. 55
