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 Send not away those who call on their Lord morning and evening, seeking His face. In naught art thou accountable for them, and in naught are they accountable for thee, that thou shouldst turn them away, and thus be (one) of the unjust. 52 Thus We have tried some of them with others, that they might say: "Is it these (poor believers) that Allah has favoured from amongst us?" Does not Allah know best those who are grateful? 53 And when those come to you who believe in Our verses, say, "Peace be upon you. Your Lord has decreed upon Himself mercy: that any of you who does wrong out of ignorance and then repents after that and corrects himself - indeed, He is Forgiving and Merciful." 54 And thus clearly do We spell out Our messages: and [We do it] so that the path of those who are lost in sin might be distinct [from that of the righteous]. 55
