Worship; acts of devotion; service; pl. ibadat. The religious duties of worship incumbent on all Muslims when they come of age and are of sound body and mind. They include the pillars of Islam—profession of faith (shahadah), canonical prayer (salat), charity (zakah), fasting (sawm), and pilgrimage to Mecca (hajj)—as well as striving to live in the path of God and the condition of purity (taharah) required for worship and Quran recitation. Because they are of central importance to the Muslim community, the ibadat form the first subject matter of Islamic jurisprudence and most collections of prophetic traditions (hadith).
