Shia Muslims are one of the two main branches of Islam, the other being Sunni Muslims. They believe that leadership of the Muslim community should have stayed within the family of the Prophet Muhammad, specifically with his cousin and son-in-law, Ali. This belief shapes their religious practices and community structure. Shia Muslims make up about 10-20% of the global Muslim population, with significant communities in countries like Iran, Iraq, and Bahrain. They celebrate unique religious events, such as Ashura, which commemorates the martyrdom of Imam Hussein, the grandson of Muhammad, and is a central figure in Shia faith and identity.
