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 call upon their Lord in the morning and the evening, they desire only His favor; neither are you answerable for any reckoning of theirs, nor are they answerable for any reckoning of yours, so that you should drive them away and thus be of the unjust. 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 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
