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 Do not turn away those who supplicate their Lord morning and evening, seeking His magnificence. You are not accountable for them in the least, nor they for you at all. If you drive them away you will only be 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 communications come to you, say: Peace be on you, your Lord has ordained mercy on Himself, (so) that if any one of you does evil in ignorance, then turns after that and acts aright, then He is Forgiving, Merciful. 54 And Thus We expound revelations so that the way of the culprits may be shown up. 55
