And warn with it those who fear to be brought before their Lord that they have no guardian or intercessor, other than Allah, in order that they are cautious. 51 And drive not away those who call upon their Lord morning and evening, seeking His countenance. Not on thee is aught of their reckoning, nor on them aught of thine reckoning, so that thou mayest drive them away and thus become of the wrong-doers. 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 do We make distinct the communications and so that the way of the guilty may become clear. 55
