Muhammad bin Umar narrates the same from his shaykhs. The virtues of Sa'd bin Khaythamah, who was one of the chiefs (nuqaba').

It is narrated from Sufyan that the chiefs (nuqaba') were twelve men, among whom were Sa'd bin Ubadah, Sa'd bin al-Rabi' and Sa'd bin Khaythamah; then he mentioned the rest of them.

Sulayman bin Aban narrates from his father that when the Messenger of Allah (peace and blessings be upon him) set out for Badr, Sa'd bin Khaythamah and his father both intended to go out with him. This was mentioned to the Prophet (peace and blessings be upon him), and he (peace and blessings be upon him) ordered that only one of them should go. So they cast lots, and the lot fell to Sa'd. He went with the Prophet (peace and blessings be upon him) to Badr and was martyred there. Then his father Khaythamah was martyred the following year on the day of Uhud.

Muhammad bin Umar narrates from his shaykhs concerning Sa'd bin Mu'adh that he was a Khazraji Ansari, and his kunyah was Abu Amr. On the day of the Battle of the Trench (Khandaq), the banner of the tribe of Aws was with him. He was struck by an arrow in the vein of his arm (al-akhal), which severed it, and blood began to flow. This happened in the fifth year of the Hijrah.

It is narrated from Abdullah bin Ka'b bin Malik that the one who shot the arrow at Sa'd bin Mu'adh on the day of the Battle of the Trench was Hibban bin Qays Ibn al-'Ariqah of Banu Amir bin Lu'ayy. When he shot the arrow, he said: Take it, and I am Ibn al-'Ariqah. Sa'd said: "May Allah scorch your face in the Fire." Then Sa'd lived for about a month after that wound, until he gave judgment concerning Banu Qurayzah by the command of the Messenger of Allah (peace and blessings be upon him) and returned to Madinah. Then his wound burst open and he passed away at night. So Jibril (peace be upon him) came to the Messenger of Allah (peace and blessings be upon him) and said: "Who is this for whom the gates of heaven have been opened and for whom the Throne of the Most Merciful has shaken?" So the Prophet (peace and blessings be upon him) went to Sa'd and found that he had passed away.
