And Ali is the Ali that we're talking about where the word Shia, Shiatu Ali, comes from, party of Ali, because Ali is considered the second Muslim. He is one of the early followers of Muhammad. As you can see, he is Muhammad's cousin. He grows up in the same household with Muhammad, with Abu Talib, and he is also Muhammad's son-in-law. He marries Fatima, and they have several children, two of which are Hassan and Hussein, who figure very prominently in the narrative I'm going to talk about in this video and the next. Now the other figures that you see here, you have Abu Bakr, who was a close companion of Muhammad, also one of the early Muslims, and you can see he was a little bit younger than Muhammad, and they are connected through Aisha. Muhammad marries Aisha after the death of Khadijah, and Aisha is a significant figure in early Islam.
