The term "Khalifah" (or "Caliph") refers to a leader in the Islamic community who is considered a successor to the Prophet Muhammad. The Khalifah is responsible for upholding Islamic law and guiding the community in spiritual and political matters. This role emerged after the death of Muhammad in 632 CE, leading to the establishment of the Rashidun Caliphate, which included the first four caliphs known for their close association with the Prophet. Khalifahs are seen as both religious and political leaders, tasked with maintaining unity among Muslims and expanding the Islamic state. The concept of the Khalifah has evolved over time, influencing various Islamic empires, such as the Umayyad and Abbasid dynasties. The title has significant historical and cultural importance in the Muslim world, symbolizing leadership and authority.
