Janb

Overview

Janb is reported as one of the sections of Qaḥṭān, with its country placed in the south of Najd and the country toward ʿAsīr. It describes a historical section as reported, and this page makes no claim about any modern family. The name, however, is an old one, and that is where care is needed.

The classical Janb is not this section

The genealogists of the classical books enter a Janb among the Yemeni tribes of Madhḥij — a name they treat as covering several Madhḥijī sections together. That is a name in the books of the fourth to ninth centuries of the Hijra, in Yemen. The section of Qaḥṭān called Janb in modern reports is a different thing, in a different country and a much later arrangement. That the two share a name is a fact about names; it is not evidence that the one continues the other, and no source this reference is permitted to cite makes that connection. Continuity between an old tribal name and a modern group bearing it has to be shown, not assumed, and here it is not shown.

The name

Ibn Manẓūr enters the root j-n-b for the side or flank of a thing and for the one who is beside you. The name is thus an ordinary Arabic word, which is part of why it recurs. The lexicon explains the word and not the naming, and this page does not turn the one into the other.

On sources

Ibn Ḥazm and al-Qalqashandī are cited here for the classical Madhḥijī name only, and the citation notes say so. Neither of them documents the modern section of Qaḥṭān, which postdates them; what is reported about it comes from oral tradition and later writing outside the permitted sources. The page records the name in both its bearings, and no descent.

On lineage

Branch lists and affiliations here are given as reported, and the genealogists differ among themselves. 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.
