Ibn Shihab narrates, among the names of those of the Ansar from Banu Sa'idah who were martyred on the day of Yamamah: Sayyiduna Usayd bin Yarbu' (may Allah be pleased with him).
Sayyiduna Usayd bin Malik Abu Amrah al-Ansari (may Allah be pleased with him) - it is also said: Bashir bin Amr bin Mihsan; and it is said: Tha'labah bin Amr bin Mihsan; and it is said: Amr bin Mihsan, of Banu Mazin bin al-Najjar - and it is said that Abu Amrah gave Sayyiduna Ali (may Allah be pleased with him) one hundred thousand dirhams on the day of Siffin, with which he helped him on the day of (the Battle of) the Camel, and he was killed on the day of Siffin.
