Yusuf had been instructed by the caliph to take charge of the campaign against the Qarmatians of Bahrain in 926.

Yusuf's army, despite having a large numerical advantage, is defeated by the Qarmatians near Kufa in 927.

The Sajid is captured; he will be killed the following year.

In Azerbaijan, he is succeeded by his nephew Abu'l-Musafir al-Fath.

After only one and a half years of rule, however, he will be poisoned in Ardabil by one of his slaves.

The Sajid dynasty will end with his death.
