And warn therewith those who fear they shall be mustered to their Lord; they have, apart from God, no protector and no intercessor; haply they will be godfearing. 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 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 Thus do We explain the signs in detail: that the way of the sinners may be shown up. 55
