Mo was long dead before anyone started working on the body of Islamic law called "Sharia Law"
BTW, if you believe all the BS in the hadiths concerning the supposed life and times of Mo and his followers you are very gullible.
Even primitive goat herders in the Yemeni deserts don't really believe all that stuff happened.
what, you mean the bullsh!t about his momma squeezing him out, him pickin' up a fistfull of dirt and shoutin' "God is great!"?
heh.
bet you some camel-humpin' sand-rats believe every word of it.
Face it: Sharia is a concordance based on the Hadiths and the rulings of the "well directed" caliphs - all of which is based on what Mo is supposed to have said, which includes a great deal of truly horrendous crap.
