Ritual Purity in Islamic Jurisprudence (Part 7)

Purifying Agents (Mutahhirat) (1) Absolute Water, Mixed Water, and the Rulings of Purification with Water

Following the conclusion of our examination of the ten intrinsic impurities (najasaat ‘ayniyyah), we now begin the discussion on “Purifying Agents” (Mutahhirat). The first and principle purifying agent in Islamic law is water. In clarifying the rulings pertaining to water, Islamic law provides a comprehensive framework that preserves spiritual purity -allowing individuals to perform acts of worship with peace of mind- whilst fostering a rational, clean lifestyle free from obsessive-compulsive doubts (waswas).

Jurisprudential Criteria and Juristic Views

A) Fundamental Classification of Water: Absolute Water and Mixed Water

• Absolute Water (Al-Ma’ al-Mutlaq): Water that can be unconditionally termed “water” without any qualifying clause (such as tap water, well water, rainwater, sea water, and river water). This water is both intrinsically pure and a purifying agent.
• Mixed Water (Al-Ma’ al-Mudaf): Liquids that cannot be termed “water” on their own, but require a qualifying noun (such as fruit juice, rosewater, or extremely muddy water).
  • Legal Ruling: Mixed water is intrinsically pure in itself, but it is never a purifying agent (it can neither cleanse impurities nor can it be used for valid wudu or ghusl). Furthermore, upon coming into contact with the slightest trace of impurity, the entirety of it becomes impure (whether it is small or large in quantity).

B) Categories of Absolute Water and Rulings on Purification

• Flowing Water, Rainwater, and Kurr Water:
  • Definition of Kurr: Kurr water is the quantity of water that would fill a container measuring three and a half hand-spans in length, width, and depth. In conventional metric units, it equals at least 384 litres (some jurists have specified 377 or 383 litres).
  • Definition of Flowing Water (Ma’ Jari): Water that springs naturally from the earth and flows, such as spring water or subterranean aqueducts (qanat).
  • Ruling: These categories of water do not become impure immediately upon contact with an impurity, unless their colour, odour, or taste changes as a direct consequence of the impurity.
  • Purification: To purify impure vessels and garments using kurr or flowing water, a single washing (after removing the physical impurity itself) is generally sufficient. According to many contemporary jurists, squeezing the garment is not required.

• Little Water (Al-Ma’ al-Qalil):
  • Definition: Water that does not spring from the ground and is less than kurr in quantity (such as a jug or a glass of water).
  • Ruling: Upon coming into contact with an impurity, the entirety of it becomes impure immediately, even if its colour, odour, or taste does not change.
  • Purification: To purify impure objects using little water, the water must be poured over the object and discharged (wash-water/ghusalah). In cases of contamination by urine or for vessels, washing two or three times (in accordance with juristic decrees) is necessary.

Human Dignity, Obligation, and Moral Conduct

• Safeguarding Property and the Dignity of Others during Purification: The obligation to perform purification must not result in damage to the property of others, cause unpleasant odours in shared spaces, or display disrespect towards fellow citizens.
• Observing Social Discipline: Washing and ritual purification must take place within the boundaries of civic rules and respect for both private and public space.

Safeguarding Intellect, Inner Purity, and Preventing Obsessive Doubt

• The Principle of Non-Wastefulness in Water Usage: Islamic law strictly forbids excessive water consumption and wastefulness (israf) during ghusl, wudu, and the purification of impurities.
• Countering Obsessive-Compulsive Doubts (Waswas): Sacred Islamic law defines the boundary of purification as “the removal of the physical impurity and the flow of water once or twice.” Continuing to wash after these legal conditions have been fulfilled stems from irrational suspicion and constitutes blameworthy behaviour.

Ecological Order, Public Health, and Civic Interactions

• Public Health and Cleanliness: The use of water as the primary purifying agent is not only a devotional duty, but also a guarantee of personal hygiene and community health.
• Facilitating Urban Living via Mains Water (Kurr): According to contemporary juristic decrees, piped mains water in homes and cities carries the legal status of “kurr/flowing water.” This makes the purification of garments, bodies, and vessels remarkably straightforward in modern life, removing the need for cumbersome traditional methods.

Practical Rulings on Contemporary Issues

• Purification Using Automatic Washing Machines: If an automatic washing machine is connected to mains water (kurr) during the wash cycles and washes the clothes and expels the wash-water (ghusalah) after removing the physical impurity, the clothes become fully pure, with no need for subsequent manual rinsing.
• Treated and Recycled Industrial Water: Wastewater that undergoes chemical and industrial treatment processes to regain the defining properties of absolute water is pure and purifying.
• Doubt Regarding Kurr Status: If it is unknown whether a quantity of water that was previously kurr has now decreased below the threshold, the legal presumption (asl) is that it remains kurr.

Frequently Asked Questions (According to Contemporary Authorities)

• Purifying Impure Garments in a Washing Machine:
  • Ayatollah Khamenei: If the washing machine washes and cleanses the garment, rinsing it with mains water, the clothes are pure.
  • Ayatollah Sistani: It is pure, provided that the physical impurity is removed prior to or during the wash, and it remains connected to mains water.
  • Ayatollah Makarem Shirazi: Garments washed in automatic machines that perform Islamic rinsing are pure.

• Purification with Mains (Municipal) Water:
  • Consensus of Contemporary Authorities (Khamenei, Sistani, Makarem): Mains water carries the ruling of kurr water; therefore, as soon as the water reaches the impure area and the physical impurity is removed, the area becomes pure, without requiring the squeezing of fabric or multiple wash cycles associated with little water.

Concluding Remark

As the primary purifying agent in Islamic jurisprudence, water serves as a symbol of both physical and spiritual purity. By extending the legal status of “kurr water” to modern water supply networks, Islamic law renders the process of purification smooth and accessible within contemporary life, enabling believers to maintain their devotional purity without falling into the traps of obsessive doubt or wastefulness.
