Warn by it those who fear to be gathered before their Lord, when they have no guardian or intercessor besides God, so that they may become God-fearing. 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 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 those who believe in Our verses come to you, say: 'Peace be upon you. Your Lord has decreed Mercy on Himself, if any one of you commits evil through ignorance, and then repents, and mends his ways, then He is Forgiving, the Most Merciful' 54 Thus do We explain the signs in detail: that the way of the sinners may be shown up. 55
