Banu Najjar (Arabic: بَنُو نَجَّار, "sons of the carpenter") or Banu al-Naggar is the name of several unrelated historical and modern-day tribes throughout the Arab world. The individual tribes vary in religious composition.^[1]

One Banu Najjar group is mentioned in the Charter of Medina, and the Banu Najjar of Medina were the maternal clan of Muhammad's grandfather Abdul-Muttalib.^[2] Islamic historians like Ibn Hajar al-Asqalani and al-Tabari list them as a clan of the large Banu Khazraj tribe of Medina. Al-Asqalani states that their ancestor was Taymallah ibn Thalabah ibn Amr ibn al-Khazraj.^[3][4] The Banu Najjar had at least three sub-clans.^[5]

Before Islam, the Banu Najjar of Medina practiced notably traditional Arab polytheism, and owned idols named Samul, Husa, and at-Tamm that were destroyed after the clan converted to Islam.^[5] They may have had a tribal alliance with Jews of Medina.^[6][5]

Muhammad initially settled with them when he emigrated from Mecca to Medina. The Prophet's Mosque was later built in the tribe's garden.^[7] The Banu Najjar are praised in a hadith attributed to Muhammad.^[8]
