Question: what are the differences between sunni sufi and shia?
Answer: The Sunnis believe that Muhammad did not designate a successor. But the Shiites believe he did: his cousin and son-in-law, Ali. ... Shiites and Sunnis share the Quran but have different collections of the hadith, which are the traditions and deeds of Muhammad. Shiites believe that the imams are the source for the hadith.
