What's the difference between Sunnis and Shi'a in Islam? BBC News report 20^th December 2013:

The division in Islam goes back to a dispute over who should succeed the prophet Muhammad after his death in 632. Those who wanted his position to be inherited by his closes associate became Sunnis. Those who wanted him to be followed by his descendants became Shi'a. Just is in the split in the Christian church between Catholics and Protestants, it's been as much about power as [it has been about] religion.
