Warn those who fear, through this (Qur'an), that they will be gathered before their Lord, and they will have none to protect or intercede for them apart from Him. They may haply take heed for themselves. 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 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 the faithful come to you, say to them, "Peace be upon you. Your Lord has decreed for Himself to be All-merciful. Anyone of you who commits a sin out of ignorance, then repents, and reforms himself will find that God is All-forgiving and All-merciful." 54 And Thus We expound revelations so that the way of the culprits may be shown up. 55
