Thank you for the opportunity to help you with your question!
the Shia and Sunni believe in one God, Allah. They believe in the Prophet. They
also believe in the Quran as their holy book. last but not least, they both
pray at least five times in a day, pay the zaka, fast for the month of Ramadan
and visit Mecca for pilgrimage. Also, when praying, they both direct their
faces to Mecca. Lastly, they believe in Ali as their fourth Caliph also
referred to as Sunnis or the first Imam, also known as Shia.
The key difference between the Shia and Sunni is what transpired after the death of the Prophet. The Shia believe that the Prophet had announced Ali as his heir at least two months before his impending death. Many Sunni books record the incident in which the Prophet publicly announced Ali to be his heir, returning back from the last pilgrimage or Hajj at a place called Ghadir-e-Khum, in front of ten thousand people. The Shia do not accept the three Caliphs as religious representatives after the Prophet, and call them usurpers. This is the primary difference between the Shia and the Sunni.
