Abu Mohammed Abdallah al-Adil was selected as sultan of Morocco following the 1223 strangulation of the previous Almohad sultan, Abdul-Wahid I. Abdullah's vizier was Abû Zayd Abî Muhammad ben Abî Hafs, who had previously served his father, Muhammad an-Nasir, and his brother,Yusuf II, as governor of Ifriqiya.

During Abdullah's reign, there were two pretenders to the Moroccan throne: his brother Abu al-Ala Idris al-Mamun, supported by Ferdinand III of Castile, and another brother, Yahyâ al-Mu`tasim, supported by the sheikhs of Marrakesh.

In 1227, Abdullah was drowned in a palace bathtub and was succeeded by his son Yahya.
