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 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 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 who believe in Our revelations come to you, say to them: "Peace on you." Your Lord has prescribed grace for Himself, so that in case one of you commits evil out of ignorance, then feels repentant and reforms, He may be forgiving and kind. 54 And Thus We expound revelations so that the way of the culprits may be shown up. 55
