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 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 And when those who believe in Our signs come to thee, say, 'Peace be upon you. Your Lord has prescribed for Himself mercy. Whosoever of you does evil in ignorance, and thereafter repents and makes amends, He is All-forgiving, All-compassionate.' 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
