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 invoke their Lord in the morning and the evening, seeking His pleasure all the time. You are by no means accountable for them just as they are by no means accountable for you. If you still drive them away, you will become among 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 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 thus do We detail the verses, and [thus] the way of the criminals will become evident. 55
