Question

Quizplus · Accepted Answer

Shia Islam holds the belief that all caliphs (or Imams, in their terminology) must be direct descendants of Ali, who was the cousin and son-in-law of the Prophet Muhammad. This belief is a fundamental difference between Shia and Sunni Islam, with the latter accepting the first four caliphs as rightly guided and not emphasizing a hereditary principle for leadership.
