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 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 tried some of them with others, that they might say: "Is it these (poor believers) that Allah has favoured from amongst us?" Does not Allah know best those who are grateful? 53 When those who believe in Our revelations come to you, say, "Peace be upon you. Your Lord has taken it upon Himself to be merciful. So that if any one among you does evil in ignorance and repents thereafter and makes amends, then He is most forgiving and ever merciful." 54 And thus do We make distinct the communications and so that the way of the guilty may become clear. 55
