The Islamic branch of Shia is a denomination of Islam that is based on the teachings of the Prophet Muhammad and his family. It is the second largest branch of Islam, with approximately 10-15% of the world's Muslim population being Shia. Shia Muslims believe in the infallibility of the Imams, or spiritual leaders, and emphasize the importance of justice and equality. They also believe in the concept of taqiyya, which is the practice of concealing one's true beliefs in order to protect oneself from harm.
