And warn hereby those who fear lest they be gathered unto their Sustainer with none to protect them from Him or to intercede with Him, so that they might become [fully] conscious of Him. 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 And thus We have tried some of them through others that the disbelievers might say, "Is it these whom Allah has favored among us?" Is not Allah most knowing of those who are grateful? 53 When those come to thee who believe in Our signs, Say: "Peace be on you: Your Lord hath inscribed for Himself (the rule of) mercy: verily, if any of you did evil in ignorance, and thereafter repented, and amend (his conduct), lo! He is Oft-forgiving, Most Merciful. 54 Thus distinctly do We explain Our signs that the way of sinners may become distinct. 55
