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 And do not drive away those who invoke their Lord in the morning and the evening, seeking His pleasure all the time. You are by no means accountable for them just as they are by no means accountable for you. If you still drive them away, you will become among the wrong-doers. 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 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 And thus clearly do We spell out Our messages: and [We do it] so that the path of those who are lost in sin might be distinct [from that of the righteous]. 55
