Salah (Arabic: ٱلصَّلَاةُ, romanized: aṣ-Ṣalāh) is the principal form of worship in Islam. Facing the Kaaba in Mecca, it consists of units called rak'ah (specific set of movements), during which the Quran is recited, and prayers from the Sunnah are typically said. The number of rak'ah varies from prayer to prayer. Minor details of performing salah may differ according to the madhhab (school of Islamic jurisprudence) of the person performing it.
