Al-Harith al-Aʿwar said: I heard ʿAli, may Allah be pleased with him, say from the pulpit: “A man may leave his family and not return to them until he has done a deed by which he merits Paradise; and a man may leave his family and not return to them until he has done a deed by which he merits the Fire.” He then recited: “On the Day when some faces will be whitened and some faces blackened”—the verse—and then proclaimed: “They are those who disbelieved after faith—by the Lord of the Kaʿbah!”
