خِلَافَةُ الْخُلَفَاءِ الرَّاشِدِينَ
The caliphate of the Rightly Guided Caliphs.
A caliph is not a successor to the Prophet’s prophethood or revelation. The office concerns maintaining religious and communal affairs after him. Its holder leads the community but does not thereby gain revelation or infallibility.
The distinction matters: political leadership is not a new form of prophethood. After the completion of prophethood, communal government proceeds through religious norms and human consultation.
