Preach the Quran to those who are concerned about the Day of Judgment at which time they will be brought before their Lord. Tell them that their only guardian and intercessor is God so that they may become pious. 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 In this way We try some of them by means of others, so that they may ask, "Are these [lowly ones] whom God has singled out for His favours from among us? Does God not know best who are the grateful ones?" 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 do We make distinct the communications and so that the way of the guilty may become clear. 55
