History of Shia Islam

Shi‘a Islam, also known as Shi‘ite Islam or Shia, is the second largest branch of Islam after Sunni Islam. Shias adhere to the teachings of Muhammad and the religious guidance of his family or his descendants known as Shia Imams. Muhammad's bloodline continues only through his daughter Fatima Zahra and cousin Ali who alongside Muhammad's grandsons comprise the Ahl al-Bayt. Thus, Shias consider Muhammad's descendants as the true source of guidance along with the teaching of Muhammad. Shia Islam, like Sunni Islam, has at times been divided into many branches; however, only three of these currently have a significant number of followers, and each of them has a separate trajectory.
