Abu Murrah, the freed slave of Aqil (may Allah have mercy on him), narrates from Sayyidah Umm Hani (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) came to her on the day of the Conquest, took a bath, then prayed eight rak'ahs of Duha (the forenoon prayer) in a single garment, crossing its two ends over each other. Then I said: "O Messenger of Allah! I have granted protection to my in-laws, the two sons of Hubayrah, and my brother claims that he will kill them." The Messenger of Allah (peace and blessings be upon him) said: "We too have granted protection to whomever Umm Hani granted protection."
