After Muhammad's death in 632 CE, the Medinan Ansar debated which of them should succeed him in running the affairs of the Muslims while Muhammad's household was busy with his burial.
According to Sunni Muslims, the term "Rashidun Caliphate" is derived from a famous[REF] hadith of Muhammad, where he foretold that the caliphate after him would last for 30 years[REF] (the length of the Rashidun Caliphate) and would then be followed by kingship [REF].
