The concept of the "Finality of Prophethood" refers to the belief that the last prophet sent by God to humanity is Prophet Muhammad. This idea is central to Islam and signifies that no new prophets will come after him, completing the line of prophetic messages. This belief emphasizes that the teachings of Prophet Muhammad are meant to guide humanity until the end of time. Followers of Islam view the Qur'an, revealed to him, as the final and complete scripture, providing comprehensive guidance for all aspects of life.
