Nizar ibn Maadd ibn Adnan

Nizar ibn Ma'add ibn Adnan was the common ancestor of most of the northern Arab tribes, according to the Arab genealogical tradition. As a result, the term 'Nizar', or Nizariyya (نزارية), has been used as a loosely defined name for a group of tribes, most commonly the Rabi'a and Mudar tribes, but occasionally extended to include others.
