"샤하다" (Shahada) is the Islamic declaration of faith, stating that "There is no god but Allah, and Muhammad is His messenger." This statement is fundamental to the beliefs of Islam and signifies a person's entry into the Muslim community. Reciting the 샤하다 sincerely is one of the Five Pillars of Islam, which are essential acts of worship and practice for Muslims. It emphasizes the oneness of God and the importance of the Prophet Muhammad in guiding followers in their faith and daily lives.
