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 call upon their Lord at morning and evening desiring His countenance; nothing of their account falls upon thee, and nothing of thy account falls upon them, that thou shouldst drive them away, and so become one of the evildoers. 52 Thus We have tried some of them with others, that they might say: "Is it these (poor believers) that Allah has favoured from amongst us?" Does not Allah know best those who are 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 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
