Cool, thanks for the hadith links, I bookmarked them all and will hopefully get to them after finals at the end of the month

Incidentally,
all of my Muslim friends are Sunni, could you maybe explain a bit what the differences are between Sunni and Shiite? I know that there were
disagreements in the past based disagreements over who should be caliph, which caused the split in the first place. I've also heard that one of the
main differences is that Shiites have the Ayatollahs and other religious leaders as a kind of intermediary, sort of like priests in Christian
religions, whereas Sunnis don't have anything like that.
