Sunni-Shia divide

The Sunni-Shia divide is a major sectarian split in Islam that originated after the death of the Prophet Muhammad in 632 AD. Sunnis, who make up about 85-90% of Muslims, believe that the leader (caliph) should be chosen by consensus among the community. Shias, comprising about 10-15%, argue that leadership should stay within the Prophet's family, specifically through his cousin and son-in-law, Ali. This disagreement over succession led to differing beliefs and practices, contributing to historical conflicts and cultural differences that persist in various regions today.
