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 send away those who call upon their Lord morning and afternoon, seeking His countenance. Not upon you is anything of their account and not upon them is anything of your account. So were you to send them away, you would [then] be of the wrongdoers. 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 verses come to you, say: 'Peace be upon you. Your Lord has decreed Mercy on Himself, if any one of you commits evil through ignorance, and then repents, and mends his ways, then He is Forgiving, the Most Merciful' 54 And this is how We explain Our verses clearly and so that the way of the criminals become well exposed. 55
