Fights between Sunni and Shia or Shiite Muslims have been a historical domain covered by political authorities. These authorities want to maintain the huge division among Muslims for political reasons and minor disagreements on Islamic understanding. Therefore, the whole world notices the conflict between Sunni and Shia Muslims which caused the death of millions of people at the beginning of the conflict. The first article discussed the begging of the Islamic religion founded by the Prophet Muhammad which left a huge struggle among his people over who should succeed the highest position of Islam. The author states that Muhammad's daughter Fatima did not agree with Abu Bakr as the new leader of Islam. Fatima thought that her husband Ali Bin Abitalib, who is also Muhammad's cousin and father of her grandchildren, should place the leadership after the Prophet Muhammad. At that point Shia and Sunni Muslims were separated in different directions. Sunnis believed that the legitimate leaders of Islam were the leaders who ruled after the death of Muhammad (Abu Bakr-Umar-Othman-Ali). On the other hand the Shiites believed that Ali should have been the first leader of Islam after the death of Muhammad and that the first three leaders illegitimately took over the leadership of Ali. Ali took over the leadership of the Islamic world after Othman's murder. The Umayyah family was against Ali's leadership and implicated Ali in Othman's murder. Therefore, Ali had to fight his enemies during the first five years of his leadership. Muawiya Bin Umayyah is the ruler of Syria, self-proclaimed leader of Islam after Ali's death. So Yazid Bin Muawiya inherited the leadership from his father. Yazid orders his army to kill Mohammed's nephew Husain bin Ali and his family. Therefore... middle of the paper... God will always save the Quran from variations. Even Hezb'allah did not set out to avenge hundreds of years of oppression and marginalization. Indeed, Hezb'allah together with the Lebanese army helped protect Lebanese territory from many wars with Israel. However, the second article did not contain much information to establish the main reason for the differences between Sunnis and Shiites. He had a wrong idea of ​​the meaning of the caliphs. The Caliph does not have to be a leader of all Islamic nations. Caliph is an Arabic name for a leader, there is nothing special about the word, unless you have a good sense of the meaning of the word. Islamic aversions are very deep and have followed our ancestors, which makes the aversions even more difficult to resolve. Muslim groups must believe in common essential beliefs and forget simple disagreements to live a peaceful life.
