The Division of Islam is a major religious schism that occurred in the 7th century CE. It is divided into two main branches, Sunni and Shia. Sunni Muslims constitute the majority of the Islamic population and adhere to the teachings of the Quran and the Sunnah. Shia Muslims, on the other hand, follow the teachings of the Quran and the Hadith, as well as the teachings of the Imams. Both branches of Islam share the same core beliefs, but differ in their interpretation of certain aspects of Islamic law and practice.
