This clan of the Ansar had as its leader ʿAmr ibn Ṭalḥah—one of the Banu al-Najjar and a member of the branch descending from ʿAmr ibn Mabdhūl, whose personal name was ʿĀmir ibn Mālik ibn al-Najjar. Al-Najjar is Taym-Allah ibn Thaʿlabah ibn ʿAmr ibn al-Khazraj ibn Ḥārithah ibn Thaʿlabah ibn ʿAmr ibn ʿĀmir.

Ibn Hisham says: ʿAmr ibn Ṭalla is ʿAmr ibn Muʿāwiyah ibn ʿAmr ibn ʿĀmir ibn Mālik ibn al-Najjar. Ṭalla was his mother, the daughter of ʿĀmir ibn Zurayq of the Khazraj.

Ibn Isḥāq relates: A man of the Banu ʿAdiyy ibn al-Najjar named Aḥmar came upon one of Tubbaʿ’s men who was cutting a cluster of dates. Striking him with his sickle, he killed him, saying, “The dates belong to the one who did the pollination!” This only increased Tubbaʿ’s anger against them, and fighting broke out. The Ansar say that they fought him by day and entertained him at night, which impressed him, and he would remark, “By Allah, these people are truly generous.” Ibn Isḥāq also transmitted from the Ansar that Tubbaʿ’s real anger was toward the Jews because they had barred him from them.

Al-Suhaylī comments: It is also said that he actually came to support the Ansar—his kinsmen—against the Jews who had settled among them in Madinah under certain agreements but then broke them and behaved arrogantly; Allah knows best.

Ibn Isḥāq continues: While Tubbaʿ was thus engaged in fighting them, two rabbis from among the Jewish scholars of the Banu Qurayzah came to him.
