An-Nasir Muhammad bin Yusuf (died August 8, 1488) was a contender for the Zaidi state in Yemen, whose term as imam is counted from 1474 to 1488.
From there he made his da'wa (call for the imamate), spreading the message to San'a, Falala and other Zaidi areas.
Nevertheless, the people of the traditional centre of the Zaydiyyah community, Sa'dah, refused to support him and instead proclaimed al-Hadi Izz ad-Din.
Neither of the claimants was able to control the key city San'a, which was in the hands of a fourth imam, al-Mu’ayyad Muhammad, since 1464.
[3] An-Nasir Muhammad died after a fairly obscure tenure in 1488, and was buried in the dome in Thula.
