And warn with it those who fear to be brought before their Lord that they have no guardian or intercessor, other than Allah, in order that they are cautious. 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 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 And when those who believe in Our messages come unto thee, say: "Peace be upon you. Your Sustainer has willed upon Himself the law of grace and mercy - so that if any of you does a bad deed out of ignorance, and thereafter repents and lives righteously, He shall be [found] much-forgiving, a dispenser of grace." 54 And Thus We expound revelations so that the way of the culprits may be shown up. 55
