this was already discussed before fefee...anyways, i dont know y did u put this thread...however, i would respond u just the major difference..

Sunni : believes in one & only Allah & only call him for help.

Shia : believes in Allah but also believes in other "Hassan, hussain, Ali etc." which is contradictory to Sunnis.
