Islam was introduced to the Horn of Africa early on from the Arabian peninsula, shortly after the hijra. Zeila's Masjid al-Qiblatayn (Two-mihrab Mosque) dates to the 7th century, and is the oldest mosque in the city. In the late 800s, Al-Yaqubi wrote that Muslims were living along the northern Somali seaboard. Among these early migrants was Abdirahman bin Isma'il al-Jabarti, the forefather of the Darod clan family.Al-Maqrizi noted that a number of the Muslims settled in the Zeila-controlled Jabarta region, and from their slowly expanded into the hinterland. The Jeberti in Ethiopia and Eritrea trace descent from these early migrants. The term Jeberti in Eritrea and Ethiopia is also sometimes used generically to refer to all Muslim inhabitants of the highlands.
