Give this warning to those in whose (hearts) is the fear that they will be brought (to judgment) before their Lord: except for Him they will have no protector nor intercessor: that they may guard (against evil). 51 And do not drive away those who call upon their Lord at morning and evening desiring His countenance; nothing of their account falls upon thee, and nothing of thy account falls upon them, that thou shouldst drive them away, and so become one of the evildoers. 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 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 Thus We make plain Our signs, so that the path of the evil-doers might be laid bare. 55
