When his troops clashed with the enemy they broke ranks and fled (1); al-Andalus was thrown into disarray, wrongdoing proliferated, and many of the Murābiṭūn were slain. He himself grew slack, content with the title alone. He turned to acts of devotion but neglected his subjects and proved incapable, until it is related that he raised his hands and prayed, “O Allah, appoint for this affair someone who has the strength to shoulder it.”

He was further tried with oppressive deputies. Then Ibn Tūmart rebelled against him; ʿAbd al-Muʾmin fought him, gained the upper hand, seized the lands, and the days of the Mulaththamūn came to an end (2). He died—may Allah have mercy on him—in 537 AH.

Authority then passed to his son Yūsuf, who resisted ʿAbd al-Muʾmin for a time, but eventually withdrew to Wahrān. His forces scattered, the Almohads captured him, and he perished in 540 AH.

Elsewhere I have recorded that the one who ruled after ʿAlī was his son Tāshfīn (3). He fought the Almohads for some time, then took refuge in Wahrān, and, according to that account, he died in Ramaḍān of the year nine (4), after which they crucified him.
