 Following al @-@ Adil 's death in 1218 and the death of Haditha a few years later , the imarat al @-@ ʿarab was divided by Sultan al @-@ Kamil ( r . 1218 – 1238 ) between Haditha 's sons Mani and Ali , who founded the independent Al Ali branch of Al Fadl , and their kinsman , Ghannam ibn Abi Tahir of the Al Faraj clan . As Mani 's position was bolstered by his cooperation with the Ayyubids in their military campaigns and keeping the Bedouin in check , al @-@ Kamil dismissed Ghannam and Ali , leaving Mani as the sole amir al @-@ ʿarab . When Mani died in 1232 / 33 , he was succeeded by his son Muhanna I after an agreement between the Ayyubid emirs of Homs and Damascus , al @-@ Mujahid Shirkuh II and al @-@ Ashraf Musa , respectively , without input from the sultan of Egypt . From this period until 1260 , only scant information is available about the imarat al @-@ ʿarab . However , it is known that in 1240 , Muhanna I was replaced by Tahir ibn Ghannam by the Ayyubid regent of Aleppo , Dayfa Khatun , for Tahir 's support against her dynastic opponents . Some years later , the title was bestowed on Ali or his son Abu Bakr .
