Banu Najjar was a clan of the Banu Khazraj tribe in Yathrib (Medina), known for their support of the Islamic prophet Muhammad as part of the Ansar, the helpers who aided Muhammad after his migration to Medina. They played a significant role in early Islamic history, with notable members such as Abu Ayyub al-Ansari, a close companion and standard-bearer of Muhammad. The clan's descendants spread across the Arabian Peninsula and beyond, including the Indian subcontinent.
