And warn by the Qur'an those who fear that they will be gathered before their Lord - for them besides Him will be no protector and no intercessor - that they might become righteous. 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 And thus do We make distinct the communications and so that the way of the guilty may become clear. 55
