Muhammad X (; 1415âÂÂ1454) was once thought to be the eighteenth Nasrid dynasty ruler of the Emirate of Granada.
Traditionally, historians have identified this person as Abu 'Abd Allah Muhammad b. 'Uthman, ruling as Muhammad X. This assessment was based on Castilian chronicles which identified him only as el Cojo ("the Lame One"). However, following publication of a new Nasrid-era Arabic source, Ibn c ÃÂá¹£im's Junnat al-Rida, it has been shown that he was actually Yusuf b. Ahmad ruling as Yusuf V.
