A slave belonging to Ibn Umar ran away and joined the Byzantines. Khalid bin Walid captured him and returned him to Abdullah. A horse of Ibn Umar's also bolted and went over to the Byzantines. It was captured, and they returned it to Abdullah.
أن عبدا لابن عمر أبق، فلحق بالروم، فظهر عليه خالد بن الوليد، فرده على عبد الله، وأن فرسا لابن عمر عار، فلحق بالروم، فظهر عليه، فردوه على عبد الله.
Bukhari narrated it in the Book of Jihad and Expeditions (3068) from Muhammad bin Bashshar, who said, we were told by Yahya, Ubaydullah said, Nafi informed me, and he related it.As for what has been narrated from Uthman bin Abu Hazim, from his father, from his grandfather Sakhr, that the Messenger of Allah ﷺ raided Thaqif. When Sakhr heard of this, he rode out with cavalry to support the Prophet ﷺ, but found that the Prophet of Allah ﷺ had already withdrawn without having conquered them. So Sakhr made a covenant with Allah and a solemn pledge that day that he would not leave that fortress until they submitted to the judgment of the Messenger of Allah ﷺ. He did not leave them until they submitted to the judgment of the Messenger of Allah ﷺ. Sakhr then wrote to him, "To proceed, Thaqif has submitted to your judgment, O Messenger of Allah, and I am coming to them while they still have cavalry with them."The Messenger of Allah ﷺ then ordered that prayer be called with the congregation gathered, and he offered ten supplications for Ahmas, saying, "O Allah, bless Ahmas in its cavalry and its men."The people came to him, and Mughira bin Shuba spoke up, saying, "O Prophet of Allah, Sakhr has taken my aunt, though I have entered into what the Muslims have entered into." So the Prophet called Sakhr and said, "O Sakhr, when people accept Islam, their blood and their property are protected. So hand over to Mughira his aunt." So he handed her over to him.The Prophet of Allah ﷺ also asked about a water source belonging to Banu Sulaym, who had fled from Islam and abandoned that water source. Sakhr said, "O Prophet of Allah, let me and my people settle there." The Prophet said, "Yes." So Sakhr settled there, and the Sulaym people then accepted Islam.They came to Sakhr and asked him to give them back the water, but he refused. So they went to the Prophet ﷺ and said, "O Prophet of Allah, we have accepted Islam and went to Sakhr so he would give us back our water, but he refused."The Prophet went to him and said, "O Sakhr, when people accept Islam, their property and their blood are protected. So give the people back their water." Sakhr said, "Yes, O Prophet of Allah."I saw the face of the Messenger of Allah ﷺ change color, turning red with shame, because of his having taken the girl and having taken the water.This narration is not sahih. Abu Dawud narrated it (3067), and Bayhaqi transmitted it through his route (9/114), from the narration of Firyabi (who is Muhammad bin Yusuf), who said, we were told by Aban bin Abdullah bin Abu Hazim, who said, I was told by Uthman bin Abu Hazim, from his father, from his grandfather Sakhr, who related it. Sakhr is the son of Aylah.Mizzi said in Tuhfat Ashraf (4/160), "This is also how Abu Naeem narrated it from Aban." In its chain is Uthman bin Abu Hazim, from whom Aban narrated, and no one has confirmed his reliability except that Ibn Hibban mentioned him among the reliable narrators in his book. For this reason Ibn Hajar said, "Acceptable," meaning when corroborated, but I have found no corroborating narration for him.His father, Abu Hazim bin Sakhr, was narrated from by his son Uthman, and no one has confirmed his reliability, so his status is unknown. For this reason Ibn Hajar said, "Obscure."Aban bin Abdullah bin Abu Hazim is truthful but weak in his memory, and there is disagreement regarding his chain of transmission. Abu Naeem included this narration in the biography of Sakhr bin Aylah in Marifat Sahabah, as did Ibn Hajar in Isabah, and Mizzi in Tuhfat Ashraf (4/160). Mizzi said, "The version narrated by Firyabi and Abu Naeem is more sahih."This hadith has been declared daif by more than one scholar, including Bayhaqi in Sunan al-Kubra (9/115) and Ishbili in his Ahkam Wusta (3/74), a judgment with which Ibn Qattan concurred in Bayan Wahm wal-Iham (3/260).
