Abu'l-Musafir al-Fath (died 929) was the last Sajid amir of Azerbaijan (928–929).

In 928 Abu'l-Musafir was invested with the government of Azerbaijan by the caliph after Abu'l-Musafir's uncle Yusuf Ibn Abi'l-Saj was killed.

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

The Sajid dynasty came to an end with his death; he was succeeded as governor by Wasif al-Shirvani.
