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 And do not drive away those who call upon their Lord in the morning and the evening, they desire only His favor; neither are you answerable for any reckoning of theirs, nor are they answerable for any reckoning of yours, so that you should drive them away and thus be of the unjust. 52 As such We have made some of them a means for testing others, so that they should say: 'Are those whom Allah favors amongst us' But does not Allah best know the thankful? 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 We make plain Our signs, so that the path of the evil-doers might be laid bare. 55
