Nasir ad-Din al-Qasri Muhammad ibn Ahmad, also Nasir al-Qasiri, was the young son of the Sultan of Fez, Sultan Ahmad.
In 1545, his father Sultan Ahmad was taken prisoner by his southern rivals the Saadians.[1] His successor, Ali Abu Hassun, regent for Nasir al-Qasiri, decided to pledge allegiance to the Ottomans in order to obtain their support.[1]
He ruled with a regent from 1545 to 1547 during the imprisonment of his father by the Saadians.
