Salim narrates from his father (Sayyiduna Abdullah bin Umar, may Allah be pleased with them both): When Sayyiduna Ghailan bin Thaqafi, may Allah be pleased with him, accepted Islam, he had ten wives. The Prophet Muhammad, peace and blessings be upon him, ordered him to keep four of them and leave the rest.
