Abbas bin Sahl bin Sa'd al-Sa'idi narrates: I saw Abu Usayd al-Sa'idi (may Allah be pleased with him) after he had lost his sight; he was short, the hair of his head and beard was white, but the hair of his head was quite thick. He died in Madinah in the year 60 AH at the age of 98, and he was the last of the people of Badr to die.

Ja'far bin Muhammad narrates from his father that Abu Usayd al-Ansari (may Allah be pleased with him) brought some captives from Bahrain. When they were lined up in rows, the Messenger of Allah (peace and blessings be upon him) stood up and looked at them, and there was a woman weeping. He (peace and blessings be upon him) asked: "What is making you weep?" She said that her son had been sold among Banu Abs. The Messenger of Allah (peace and blessings be upon him) said to Abu Usayd: "Ride out right now and bring him back." So Abu Usayd set off and brought him back. This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

Abu Usayd said (out of love and humility): "If I were one to say anything other than the truth, I would have begun with my own clan, Banu Sa'idah."

His kunyah was Abu Abd al-Rahman. He lived between the two mountains of Muzaynah, al-Ash'ar and al-Ajrad, and came to Madinah often. He died in the year 60 AH, when he was 80 years old.

Al-Harith and Bilal narrate from their father Yahya, and he from their grandfather Sayyiduna Bilal bin al-Harith al-Muzani (may Allah be pleased with him), that the Messenger of Allah (peace and blessings be upon him) granted him a piece of land as a fief and wrote a document for him: "This is the deed which Muhammad, the Messenger of Allah (peace and blessings be upon him), has granted to Bilal bin al-Harith. He (peace and blessings be upon him) has granted him the mines of al-Qabaliyyah, both their low-lying and their elevated parts, and al-Ghashiyyah, Dhat al-Nusub, and all the places of Quds where cultivation is possible, provided that he works there."
