Al-Zubayr ibn Bakkār (Arabic: أبو عبدالله الزبير بن بكار بن عبد الله بن مصعب بن ثابت بن عبد الله بن الزبير بن العوام, (788-870 CE / 172-256 AH), a descendant of Al-Zubayr ibn al-ʻAwwām, was a leading Arab Muslim historian and genealogist of the Arabs, particularly the Hijaz region. He composed a number of works on genealogy that made him a standing authority on the subject of the genealogies of the Quraysh tribe. Ibn Hajar al-Asqalani regarded him as the most reliable authority for Quraysh genealogical matters.
