Salah (Arabic: ٱلصَّلَاةُ, romanized: aṣ-Ṣalāh) is the practice of formal worship in Islam, consisting of a series of ritual prayers performed at prescribed times daily. Facing the Kaaba in Mecca, it consists of units known as rak'ah, which include a specific set of physical postures, recitation from the Quran, and prayers from the Sunnah. The number of rak'ah varies depending on the specific prayer. Variations in practice are observed among adherents of different madhahib (schools of Islamic jurisprudence).
