Abu al-Hasan, may Allah have mercy on him, says that a person asked Sayyiduna Ibn Abbas, may Allah be pleased with them both, about this issue: If a slave gives his wife two divorces, then after freeing himself wants to marry her, can he do so or not? Sayyiduna Ibn Abbas, may Allah be pleased with them both, replied: He can do so. He asked: On whose authority are you narrating this? He replied: The Prophet, peace and blessings be upon him, gave this very verdict. Abdullah narrates from his father, Imam Ahmad, may Allah have mercy on him, that someone asked Muammar: O Abu Urwah! Who is this Abu al-Hasan? He has lifted a very great rock.
