Purity is half of faith, the key to prayer, and the primary condition for the acceptance of acts of worship. It is divided into spiritual purity from polytheism and sins, and physical purity from ritual impurity and physical filth.
Purposes of Purity in Islam: The purposes of purity in Islamic jurisprudence are divided into two senses: the first is terminological and jurisprudential, referring to the intended actions themselves within the chapters of purity rulings; the second comprises teleological and spiritual purposes, which relate to the wisdom and ultimate objective behind its legislation.
- Jurisprudential (Practical) Purposes: The purposes of purity in books of jurisprudence refer to the actions for which the means (such as water and dust/earth) are legislated. The most important of these are four:
- Ablution (Wudu): To remove minor ritual impurity in preparation for worship.
- Full Ghusl: To remove major ritual impurity (such as janabah).
- Tayammum (Dry Ablution): An emergency alternative when water is missing or one is unable to use it.
- Removing Impurity: Purifying the body, clothing, and place from physical filth.
- Teleological Purposes and Legal Wisdom: The deep objectives behind legislating purity lie in educational, health, and social matters, summarized as follows:
- Compliance and Proximity: Achieving servitude to Allah the Almighty by responding to His command, regardless of other dimensions.
- Validity of Acts of Worship: Purity was legislated as a fundamental condition for the validity of the keys to prayers, reading the Mushaf, and Tawaf around the Kaaba.
- Physical Cleanliness: Removing harm and unpleasant odors, and protecting humans from diseases.
- Spiritual Refinement: Renewing bodily vitality and mental clarity, and making the Muslim feel spiritually prepared to meet Allah the Almighty.
- Beautiful Appearance: Appearing in a clean manner befitting the dignity of a Muslim human being before creation and in society.
Fundamental Pillars of Ablution: Washing the face, washing the hands up to the elbows, wiping the head, and washing the feet up to the ankles, while observing the proper order (Tartib) and continuity (Muwalat). These rulings reflect directly on the validity or invalidity of the prayer.
