Al Mannai tribes are located in the whole Persian Gulf area, especially in Qatar and Bahrain.
The mother of Hamad bin Khalifa Al Thani, the former Emir of Qatar, is from the Attiyah family.
In Qatar, the Al Mannai were historically based in the village of Abu Dhalouf.
J. G. Lorimer, a British historian, stated that in 1908 the village was inhabited by 70 families of the Al Mannai tribe.
