 "Abu Bakr al-Baghdadi, the leader of the Islamic State and self-proclaimed caliph, claims to be a descendant of Muhammad. That's not surprising since most Sunni Muslims believe only a descendant from Muhammad's tribe can be caliph. What makes Baghdadi's lineage interesting is that he claims to descend from Muhammad through ten of the twelve Shiite imams. That's an unusual and sadly ironic genealogy for a man hellbent on eradicating the Shiites."
