Shiekh Isāq Bin Ahmed was one of the Arabian Scholars that crossed the sea from Arabia to the Horn of Africa to spread Islam around 13th to 14th century .
Shiekh Isāq descended from Prophet Mohammed's daughter Fatima. Hence the Shiekh belonged to the Ashraf or Sada (titles given the descendents of the prophet).
Sheikh Isāq married two local women in Somalia that left him eight sons. The descendents of the those eight sons are the what is known as Isaaq clan at the present time. However, the Shiek left other descendents in Yemen as well.
The origin of Shiekh Isāq was traced back Iraq. Researcher and groups such as AlAshraf concluded beyond doubt the origin and the history of Shiekh Isāq. This research was based on the old books and scripts as well as DNA tests carried out on some of his descendants.
Here is Sheikh Isāq's lineage going to Banu Hashim, it is important and beneficial if you add this to his Abtirsi.
