Al-Aḥqāf

The name

A ḥiqf is a bent dune: sand that has piled and leaned over, curved along its crest. Aḥqāf is its plural, so the name means simply 'the curving dunes'. It describes a landscape, not a settlement — which is why it cannot be pinned to a point on a map, and why the sources that use it are describing country rather than drawing a border.

Where the sources place it

Yāqūt puts the Aḥqāf in the sands of the south, in the direction of Ḥaḍramawt and the country of Mahrah, toward Oman; al-Hamdānī describes the same belt of sand from the Yemeni side. They do not agree on how far it extends, and none of them fixes an edge. A stretch of dunes is being named, and that is all.

And the Empty Quarter

Modern writing often treats al-Aḥqāf and the Rubʿ al-Khālī as two names for one desert. Both halves of that need care. The Rubʿ al-Khālī is itself a recent name — the classical name for the great sands is the sands of Yabrīn — and where the older sources distinguish within them, al-Aḥqāf points to the southern reaches rather than to the whole. So a classical source that places something 'in the Aḥqāf' is pointing nearer Ḥaḍramawt and Mahrah than al-Aḥsāʾ.

In tradition

The Aḥqāf are also named in the transmitted accounts as the dwellings of ʿĀd, one of the peoples the genealogists class among the bāʾida — those held to have left no line to trace. Those are narrative accounts, not documentation, and nothing in them bears on the descent of any living family.
