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 invoke their Lord in the morning and the evening, seeking His pleasure all the time. You are by no means accountable for them just as they are by no means accountable for you. If you still drive them away, you will become among the wrong-doers. 52 In this way We try some of them by means of others, so that they may ask, "Are these [lowly ones] whom God has singled out for His favours from among us? Does God not know best who are the grateful ones?" 53 And when those who believe in Our signs come to thee, say, 'Peace be upon you. Your Lord has prescribed for Himself mercy. Whosoever of you does evil in ignorance, and thereafter repents and makes amends, He is All-forgiving, All-compassionate.' 54 Thus do We expound the revelations that the way of the unrighteous may be manifest. 55
