Zubayd ibn Ṣaʿb

Overview

This page is about the ancestral name and the position it occupies in the Madhḥijī chains, not about the tribe as a body. In the reckoning usually given, Zubayd ibn Ṣaʿb comes under Saʿd al-ʿAshīra, and so under Madhḥij and the Qaḥṭānī line. The tribal name as it is used more widely has its own page here, and the classical tribe its own again; the three overlap and the sources do not always separate them, which is why the distinction is worth setting out. Nothing on any of the three establishes a modern family's descent.

More than one Zubayd

The genealogists name a greater and a lesser Zubayd in the Madhḥijī material — Zubayd al-Akbar and Zubayd al-Aṣghar — and differ over how the two stand to each other and which of them the later tribe is counted from. Disagreement at the head of a chain is not a small matter: everything reckoned below it inherits the doubt, and two men who both trace to Zubayd may be tracing to different men of the name. This reference reports the disagreement rather than resolving it, because the sources do not resolve it either.

The name and its vowels

The root in Lisān al-ʿArab gives zabad for froth on water and zubd for the cream of milk, with zabada meaning to give; Zubayd is a diminutive formed from it, and diminutive forms are common among old Arab ancestral names. The vowelling carries real weight here. Zubayd of Madhḥij is not Zabīd, the town of the Yemeni Tihāma, and the two share a consonantal skeleton so exactly that the nisba al-Zubaydī serves both. Any attribution built on that nisba alone has already lost the information that would settle it.

On lineage

Branch lists and affiliations here are given as reported by the classical genealogists, who themselves disagree. Nothing on this page establishes any living family's descent: a shared name may reflect descent, alliance (ḥilf) or clientage (walāʾ), and the sources usually say which only when they know.
