Give this warning to those in whose (hearts) is the fear that they will be brought (to judgment) before their Lord: except for Him they will have no protector nor intercessor: that they may guard (against evil). 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 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 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 Thus We clearly set forth Our signs so that the way of the wicked might become distinct. 55
