And warn with it those who fear that they shall be gathered to their Lord-- there is no guardian for them, nor any intercessor besides Him-- that they may guard (against evil). 51 Do not send away those who call upon their Lord in the morning and in the evening, seeking only His grace. You are not by any means accountable for them, nor are they accountable for you. If you turn them away, you yourself will become one of the unjust. 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 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
