بكر بن وائل
The Banu Taghlib were originally a Bedouin (nomadic Arab) tribe that inhabited the Najd. The tribe was named after its progenitor Taghlib ibn Wa'il, also known as Dithar ibn Wa'il. The tribe belonged to the Rabi'a confederation and thus traced its descent to the Nizar branch of the Adnanites. Their full genealogy is as follows: Taghlib/Dithār ibn Wāʾil ibn Qasit ibn Hinb ibn Afṣā ibn Duʿmī ibn Jadīla ibn Asad ibn Rabīʿa ibn Nizār ibn Maʿadd ibn Adnān. Their rival and brother tribe was the Banu Bakr ibn Wa'il.
