One of the oldest local currencies attributed to Hadramawt is the Ibn Sahl coin.

​

The Ibn Sahl coin is attributed to Sayyid al-Husayn ibn Abd al-Rahman ibn Sahl, from the Al-Jamal al-Layl branch of the Alawi Sayyids of Tarim. His name is associated with the history of Tarim during the 13th century AH. He died in the city of Al-Shihr in 1274 AH.

It is strange that Tarim and Aden are mentioned together! Does this mean that Aden was part of Hadramawt?
