Overview

Banū Ẓafar is one of the houses of al-Aws at Medina, gathered with Banū ʿAbd al-Ashhal and Banū Ḥāritha under the byname al-Nabīt. The genealogists reckon it to Ẓafar ibn al-Khazraj ibn ʿAmr ibn Mālik ibn al-Aws, and most of them add that the man's given name was Kaʿb and that Ẓafar was a byname that stayed with him. The al-Khazraj in this chain is the Awsī ancestor of that name, not the tribe al-Khazraj. This page describes a historical house and makes no statement about any modern family, surname or claim of descent.

The name

Two words sit on the root ẓ-f-r and the vowelling separates them. Ẓafar, with fatḥas, is winning through and getting the better of a thing; ẓufr, with a ḍamma and a sukūn, is the nail or claw. Lisān al-ʿArab gives both, and the lexicographers connect them — the one who seizes is the one whose claws take hold. As a name it is best read in the first sense. The lexicon gives the sense of the word, not the reason a particular man was called by it.

Not Ẓafār

Ẓafar the house-name is not Ẓafār, the town of Yemen that Yāqūt records in the Muʿjam al-Buldān and that gave its name to a region in the south. They differ in vowelling, in the long alif and in everything else, and the resemblance is a matter of writing. A reader tracing an attribution should check which of the two a source means before drawing a map.

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. Where the sources report a byname displacing a given name, as here with Kaʿb and Ẓafar, the two names should not be treated as two men.

Frequently asked questions

Is the name Ẓafar or Ẓufr?

As a name it is Ẓafar, with fatḥas, from getting the better of a thing. Ẓufr with a ḍamma is the nail or claw. Lisān al-ʿArab gives both on the one root.
