Isa Bin Tarif, Chief of the Al Bin Ali Al Utbi Tribe, is a descendant of the Original Utoobee conquerers of Bahrain.
Sayyid Saeed Bin Sultan, Imam of Muscat, asked for the assistance of Shaikh Isa Bin Tarif in conquering the town of Mombasa in Kenya in 1837 with his tribe Utub Al Bin Ali. Fort Jesus in Mombasa was named after Shaikh Isa Bin Tarif after he conquered the fort. The translation of Jesus in Arabic is Isa, hence in Arabic it is called the Fort of Isa.

After helping Shaikh Mohamed in ousting Shaikh Abdulla from rulership of Bahrain, Shaikh Isa Bin Tarif and his tribe Al Bin Ali decided to move to the town of Al-Bida (known today as Doha) and re-established it after the removal of the Al-Sudan Tribe from it. In Al-Bida, Shaikh Isa Bin Tarif built a wall to the sea from both the East and West. In Al-Bida, Shaikh Isa Bin Tarif was considered as the Shaikh of Al-Bida which at that time meant the Shaikh of Qatar since power was centralised in Al-Bida.
