Yusuf bin Ahmad al-Kawneyn

Yusuf bin Ahmad al-Kawneyn, popularly known as Aw Barkhadle, Yusuf Al Kownayn, Yusuf Al Bagdhadi, and Shaykh Abu Barakat al Barbari, was a Somali Muslim scholar and traveler. Based on reference to Yusuf Al Kawneyn in the Harar manuscripts, Dr. Enrico Cerulli has suggested that Al-Kawneyn was the founder and ancestor of the Walashma dynasty that governed both Sultanate of Ifat and Adal Sultanate during the middle ages. Another genealogical tradition according to C.J Cruttenden is that Aw Barkhadle was a descendant of Ismail (Garhajis), son of Sheikh Isaaq ibn Ahmed. Several accounts indicate Shaykh Yusuf al Kownayn and Shaykh Isaaq were known to be contemporaries and in contact at the same time.
