Abdullah bin Abi Bakr bin Muhammad bin Amr bin Hazm states: We were sitting with him when mention was made of the first child born among the Ansar after the arrival of the Messenger of Allah (peace and blessings be upon him) in Madinah. He said that it was al-Nu'man bin Bashir, who was born a year and a few days, or a little less than a year, after the Messenger of Allah (peace and blessings be upon him) arrived in Madinah. Then the people mentioned Abdullah bin Abi Talhah, and he said that Sayyidah Umm Sulaym (may Allah be pleased with her) was pregnant with him on the day of the Battle of Hunayn, and he was born after the return to Madinah.

Abu Mushir states that Sayyiduna al-Nu'man bin Bashir (may Allah be pleased with him) was treacherously killed at a place between Salamiyah and Hims.

Ali bin Muhammad al-Mada'ini and others state that when al-Dahhak bin Qays was killed at Marj Rahit, in the middle of Dhu al-Hijjah in the year 64 AH during the caliphate of Marwan bin al-Hakam, al-Nu'man bin Bashir wanted to flee from Hims, where he was the governor. He had opposed (the Umayyads) and called for allegiance to Ibn al-Zubayr, so the people of Hims searched for him, killed him and cut off his head. That al-Nu'man bin Bashir heard from the Messenger of Allah (peace and blessings be upon him) is established by the narrations in the two Sahihs.
