What is the basic difference between shia's and sunnis?

Exactly what I said “It make absoultely no sense that a Person is assgined a duty and he leaves the work half done”… Means Prophet s.a.w left Quran in the best order, and if the order was so essential he would have changed it during his life.

Dont u remember those who ran away from Ohad… wether u include umar in them or not …per ur defination they were all students of Prophet s.a.w, so na-aozobillah did their teacher train em to run away from battle field ?

Can u blame Prophet s.a.w capabilities in this case ? NO …

Some students were so dumb they spent their life with Teacher like Prophet s.a.w and still didnt learn.
