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 drive not away those who call upon their Lord morning and evening, seeking His countenance. Not on thee is aught of their reckoning, nor on them aught of thine reckoning, so that thou mayest drive them away and thus become of the wrong-doers. 52 For it is in this way that We try men through one another - to the end that they might ask, "Has God, then, bestowed His favour upon those others in preference to us?" Does not God know best as to who is grateful [to Him]? 53 And when those who believe in Our messages come unto thee, say: "Peace be upon you. Your Sustainer has willed upon Himself the law of grace and mercy - so that if any of you does a bad deed out of ignorance, and thereafter repents and lives righteously, He shall be [found] much-forgiving, a dispenser of grace." 54 Thus We distinguish Our signs, that the sinners' way may be manifest. 55
