I have no idea what you speak of. Islam is fragmented along Shi'a/Sunni lines ; that is the big divide - who was the rightful heir to the prophet.Some sects are not true Islam, just like the Westboro Baptist Church is not really Baptist or Christian.
From there different interpretations of the main sects divide along how the text in the Q'uran is interpreted.
Salafism is a Sunni "fundamentalism" (sic) - larger then Wahhabism, but stressing the same puritanical practices.
OBL is old news - think al-Baghdadi ,and Zawahiri ( ISIS and AQ Core)
