A "rak'ah" is a unit of prayer in Islam that consists of a series of movements and recitations. Each rak'ah includes standing, bowing, and prostrating, along with specific verses from the Qur'an. The number of rak'ahs varies depending on the type of prayer being performed, such as the five daily prayers. During each rak'ah, worshippers express their devotion and submission to Allah. The structure of the rak'ah helps to create a rhythm in the prayer, allowing individuals to focus their thoughts and intentions. Understanding rak'ahs is essential for practicing Salah, the formal prayer in Islam.
