And warn therewith (the Quran) those who fear that they will be gathered before their Lord, when there will be neither a protector nor an intercessor for them besides Him, so that they may fear Allah and keep their duty to Him (by abstaining from committing sins and by doing all kinds of good deeds which He has ordained). 51 And do not send away those who call upon their Lord morning and afternoon, seeking His countenance. Not upon you is anything of their account and not upon them is anything of your account. So were you to send them away, you would [then] be of the wrongdoers. 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 And Thus We expound revelations so that the way of the culprits may be shown up. 55
