Their beliefs over who should have succeeded the Prophet Muhammad is the key theological difference between the two. Sunnis also have a less elaborate religious hierarchy than Shiites have, and the two sects' interpretation of Islam's schools of law is different
Shia people think that imam ali is the 1st khalifa or should be the first, because the profet Muhammed said that " I leave in you the two heavens, the Book of God, and my family" and after that the prophet rasied Imam Ali hand and said: " Whoever believe that i was the prophet should believe that Ali is the person in charge after I go meet Allah.
and so shia thinks that he is the person in charge after the prophet Muhammed.
Sunni people say that omar and abo baker are the people in charge. wich is so disrespecful to the prophet, because he said that Ali is incharge of the muslims by-step explanation:
the difference are shia believes that Imam Ali is the first khalifa and the sons of ali are the once incharge after him.
