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 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 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 When the faithful come to you, say to them, "Peace be upon you. Your Lord has decreed for Himself to be All-merciful. Anyone of you who commits a sin out of ignorance, then repents, and reforms himself will find that God is All-forgiving and All-merciful." 54 And Thus We expound revelations so that the way of the culprits may be shown up. 55
