al-Allamah Muhammad Shaf'i al-Khatib Okarawi
Types of Worship There are three types of worship, and they are:
1. Physical: that which is connected to the physical aspect, e.g. the recitation of the Noble Qur'aan, the tasbīh (praising God the Exalted) and tahlīl (acclamation of God the Exalted), the du`ā' (supplication) and istighfār (repenting), and the salāh (prayer) and sawm (fasting), etc.
2. Financial: that which is connected to the financial and monetary aspect, e.g. the zakāh (mandatory almsgiving), the sadaqāt (charities) and khayrāt (philanthropies), etc.
3. Combined (Physical and Financial): that which is a combination of both the physical and financial aspects, e.g. the hajj (annual pilgrimage to the sanctified city of Makkah al-Mukarramah to perform various religious rites), in which both the physique of an individual is necessary to reach Makkah al-Mukarramah in order to perform the rites of hajj, as well as the monetary expenditure that goes with it.
