The Great Islamic Divide

Gives you some background between the split within Islam. Just like the Christians have the Catholics, Protestants, Anglicans, Methodists, Presbyterians, etc....the Muslims have two major factions also, i.e. the Sunnis and the Shi'ites.
Can be a useful rebuttal to the view that religion helps to bond people and promotes unity and stability. Note that the catch is that this is true only if we are referring to people who share the same religious faith. Even with those who worship the same god, this is not a guarantee! Think Christianity, Judaism and Islam.
You want to know that the majority Sunnis and the minority Shi'ites are having a bit of problem in neighbouring Malaysia now.....and in Iraq, the two factions are embroiled in a major power struggle that has led to much violence and bloodshed.

Sample Qns:
