[Machine] When the Prophet ﷺ returned from Hunayn, Umar asked him about a vow that he had made during the pre-Islamic period of ignorance to observe isolation for one day. The Prophet ﷺ ordered him to fulfill it, so Ibn Umar went ahead and said, "He also sent a slave girl with me, whom he had received as booty during the Battle of Hunayn." He said, "I kept her in some of the houses of the Bedouins when I descended and suddenly found myself as a captive in the Battle of Hunayn. They were searching for me and saying, 'We have been set free by the Messenger of Allah ﷺ!' Umar said to Abdullah, 'Go and send her away.'" He said, "So I went and sent her away."
