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 Do not send away those who call upon their Lord in the morning and in the evening, seeking only His grace. You are not by any means accountable for them, nor are they accountable for you. If you turn them away, you yourself will become one of the unjust. 52 Thus We have made some of them a means for testing others so that they should say: 'Are these the ones among us upon whom Allah has bestowed His favour?' Yes, does Allah not know well who are the thankful? 53 And when those who believe in Our signs come humbly in your presence, say to them, “Peace be upon you – your Lord has prescribed mercy for Himself by His grace – that whoever among you commits a sin by folly and thereafter repents and reforms (himself), then indeed Allah is Oft Forgiving, Most Merciful.” 54 Thus do We expound the revelations that the way of the unrighteous may be manifest. 55
