Absolute and restricted water, mixtures with pure substances, dominance by quantity and properties Read the bilingual lesson for Unrestricted Water, Restricted Liquids, and Clean Admixtures and test your understanding with a focused quiz.
Lesson
1. Water as a Means of Purification
Absolute water is water that properly bears the unrestricted name “water,” including rainwater, well water, and spring water in their ordinary state.
Restricted water is a liquid normally identified by another substance, such as expressed fruit juice or concentrated broth.
The issue is not merely whether a liquid is clean. It must qualify for ritual purification, namely wudu and ghusl.
2. Permissible Sources of Water
وَالطَّهَارَةُ مِنَ الْأَحْدَاثِ جَائِزَةٌ بِمَاءِ السَّمَاءِ وَالْأَوْدِيَةِ وَالْعُيُونِ وَالْآبَارِ وَمَاءِ الْبِحَارِ.
Meaning: Purification from ritual impurity is permissible with rainwater, valley water, springwater, well water and seawater.
Purification from ritual impurity means the purification performed through wudu or ghusl.
Five sources are named. A source being rain, river, spring, well or sea does not by itself remove the water's ability to purify.
3. Quranic Evidence for Rainwater
وَيُنَزِّلُ عَلَيْكُمْ مِنَ السَّمَاءِ مَاءً لِيُطَهِّرَكُمْ بِهِ
Meaning: He sends down water from the sky to purify you thereby.
The verse explicitly mentions purification as the purpose. Rainwater is therefore, in principle, suitable for ritual purification. Reference: al-Anfal 8:11.
4. Valley, Spring and Well Water
A valley is the channel through which water flows, an ‘ayn is a spring, and a bi’r is a well.
The water may acquire a natural earthy colour or taste without necessarily losing its legal designation as water.
Contamination by impurity is a separate question, addressed in the subsequent discussion.
5. Seawater and Prophetic Evidence
هُوَ الطَّهُورُ مَاؤُهُ
Meaning: Its water is purifying.
Seawater is naturally salty, but remains suitable for wudu and ghusl.
The term tahur denotes water that is pure in itself and capable of effecting ritual purification.
6. Liquids Expressed from Plants and Fruit
وَلَا تَجُوزُ الطَّهَارَةُ بِمَاءٍ اعْتُصِرَ مِنَ الشَّجَرِ وَالثَّمَرِ،
Meaning: Purification is not permissible with liquid expressed from trees or fruits.
Expressed liquid is the juice extracted from plants and fruit.
Such a liquid may be clean and drinkable, but is not automatically unrestricted water suitable for wudu or ghusl.
7. Cleanliness Is Not the Same as Purifying Capacity
Tahir means clean in itself, whereas tahur, in this context, is water that can effect ritual purification.
Fresh fruit juice is generally clean but does not replace unrestricted water for wudu. Similarly, vinegar and broth can be clean yet unsuitable for wudu.
8. Dominance of an Added Substance
وَلَا بِمَاءٍ غَلَبَ عَلَيْهِ غَيْرُهُ
Meaning: Nor is purification permissible with water over which another substance has become dominant.
Dominance refers to the point where the additive, rather than the original water, determines the character of the mixture.
A slight admixture and one that transforms the substance are not treated identically.
9. The Decisive Test: Whether It Remains Water
The expression “water” applies where the substance retains its ordinary identity as water. If mixing transforms it into a defined beverage or preparation, it becomes restricted water.
The mere presence of some water in a substance is not enough; its continued legal character as water matters.
Jurists examine both comparative quantities and changes in properties.
10. When Water Is Transformed
فَأَخْرَجَهُ عَنْ طَبْعِ الْمَاءِ كَالْأَشْرِبَةِ وَالْخَلِّ وَالْمَرَقِ وَمَاءِ الْبَاقِلَّاءِ وَمَاءِ الْوَرْدِ وَمَاءِ الزَّرْدَجِ.
Meaning: So that it takes the liquid beyond the natural character of water, as with beverages, vinegar, broth, bean-water, rosewater and carrot-water.
The natural character of water is its legally recognised identity as water.
These are examples of transformed or prepared liquids which no longer bear the unrestricted name of water.
11. Beverages, Vinegar and Broth
Ashribah refers to beverages; khall means vinegar, and maraq means broth.
Once an added substance turns water into a prepared beverage, vinegar or broth, the liquid loses the legal character of unrestricted water.
The restriction concerns suitability for ritual purification, not necessarily the liquid's cleanliness.
12. Bean Liquid, Rosewater and Carrot Juice
Ma’ al-baqilla’ is liquid associated with cooked broad beans; ma’ al-ward is rosewater; ma’ al-zardaj is carrot liquid or juice.
They are named for substances other than ordinary water and cannot simply replace it for wudu.
A few rose petals incidentally entering water should not be confused with prepared rosewater; the former depends on whether the water retains its basic character.
13. Cooking and Complete Blending
An additive may only mix with water, or cooking and thorough blending may transform the mixture into a distinct preparation.
A concentrated decoction or broth is not automatically usable for wudu merely because it contains water.
Light contact with a clean substance is different if the liquid still genuinely remains water.
14. When a Pure Additive Changes One Property
وَتَجُوزُ الطَّهَارَةُ بِمَاءٍ خَالَطَهُ شَيْءٌ طَاهِرٌ فَغَيَّرَ أَحَدَ أَوْصَافِهِ
Meaning: Purification is permissible with water mixed with a clean substance that alters one of its properties.
Awṣāf refers to observable properties such as colour, smell and taste.
A slight change caused by a clean additive does not necessarily remove the substance’s identity as water.
15. Floodwater, Ushnan, Soap and Saffron
كَمَاءِ الْمَدِّ وَالْمَاءِ الَّذِي يَخْتَلِطُ بِهِ الْأُشْنَانُ وَالصَّابُونُ وَالزَّعْفَرَانُ.
Meaning: Such as floodwater, and water that has mixed with ushnan, soap or saffron.
Ushnan is a plant-derived cleansing agent. Saffron may lightly colour water; soap may alter its appearance.
The allowance applies where the water retains its ordinary identity and fluidity, not where the additive has transformed it.
16. Why Floodwater May Be Muddy
Ma’ al-madd refers to water associated with flooding or a rise in water flow, which may become muddy from suspended earth.
An earthy colour alone does not necessarily bar purification, provided no impurity or other disqualifying condition exists.
A change in appearance is not always a change in legal substance.
17. Water Mixed with Cleansing Agents
Ushnan and soap are cleansing materials, but their mixture with water may have different outcomes.
A mild change that leaves the liquid recognisably water does not by itself prevent ritual purification.
A concentrated soap solution that is no longer unrestricted water is a different matter; dominance and the surviving water-character determine the distinction.
18. Saffron and a Change in Colour
A few saffron strands may yellow the water without ending its status as water, so colour change alone does not always prohibit its use.
But if saffron or another substance dominates sufficiently to transform the liquid, it is no longer unrestricted water.
Colour is evidence to consider, not an invariably decisive criterion.
19. The Three Observable Properties
After an admixture, jurists examine colour (lawn), taste (ta‘m) and smell (rih).
A change caused by a clean substance is not the same legal category as contamination by impurity.
A mild effect and the formation of a dominant new preparation are different, leading jurists to discuss both properties and constituent proportions.
20. Dominance by Quantity of Components
Dominance by components considers the relative proportions of the liquids. This can be particularly relevant where observable properties do not clearly distinguish the constituents.
The commentary uses examples such as scentless rosewater and used water to explain when ratios matter.
This is not a universal rule that quantity alone resolves every mixture; the kinds of liquids and their properties also matter.
21. Dominance by Observable Properties
Dominance by properties evaluates colour, taste and smell. Milk mixed with water, for example, makes these characteristics visible.
If the additive overtakes the water’s character, the mixture ceases to be unrestricted water.
A minor change in one property, however, does not automatically mean transformation; the specific mixture remains relevant.
22. Abu Yusuf and Muhammad on Mixed Water
A transmitted Hanafi discussion associates Abu Yusuf with examining quantities and component proportions, while Muhammad is reported to emphasise apparent properties, particularly changes in colour.
Their disagreement concerns how one determines dominance after a clean additive enters water.
Both approaches address the same legal issue: whether the mixture remains unrestricted water.
23. Reconciling the Two Tests
Where mixed liquids are similar in appearance, proportion-based assessment can be more useful.
Where the other liquid is of a different kind, such as milk, observable properties may disclose its dominance more clearly.
This reconciliation applies the two tests according to the nature of the mixture rather than mechanically applying one to every case.
24. When a Solid Mixes with Water
When a solid such as earth or cleaning powder mixes with water, the water may change in appearance.
In such mixtures, liquidity and ability to flow are important criteria.
A fluid that remains recognisably water is not disqualified by every minor change, whereas a thick new compound may have a different ruling.
25. When Another Liquid Mixes with Water
When the additive is itself liquid, fluidity alone does not resolve the issue because both substances are fluid.
Jurists therefore consider whether the liquids are of the same kind, the comparative proportions and how colour, smell or taste change.
Milk, rosewater and indistinguishable liquids may require different emphases in their assessment.
26. Rosewater without Its Characteristic Scent
Rosewater that has lost its scent may be difficult to distinguish from plain water by smell.
If such a liquid mixes with water, constituent proportions become relevant to judging dominance.
This does not turn rosewater by itself into unrestricted water; the discussion concerns a mixture with ordinary water.
27. Clean Additives Versus Impurity
A clean additive raises the question of whether it dominates and changes the water’s identity.
Impurity involves a separate body of rules, including whether water is still or flowing and the effect of contamination.
This lesson concerns water mixed with a clean substance; the next topic treats impurity in water.
28. Case Study: Fruit Juice
Purely expressed fruit juice may be clear and contain natural water, but is still juice rather than unrestricted water.
It does not serve for wudu.
A slight trace of fruit material entering otherwise ordinary water is a separate mixture question, assessed by whether the water retains its identity.
29. Case Study: Tinted Water Versus Syrup
A slight saffron tint may leave water legally unchanged as unrestricted water.
A thick syrup made with substantial additives becomes a separate beverage or preparation.
Both involve clean additives, but one is a limited change in a property and the other a transformation of substance.
30. Case Study: Milk Mixed with Water
Milk mixed with water can be evaluated by visible whiteness, taste and comparative proportions.
A property-based approach examines how far milk characteristics dominate; a component-based approach considers quantities.
The result depends on whether the mixture retains the legal character of water or becomes dominated by milk.
31. The Governing Rule and Its Applications
The discussion yields three governing distinctions:
1. Unrestricted water from rain, valleys, springs, wells or seas is suitable for ritual purification.
2. Expressed juice or a transformed preparation is restricted water and unsuitable for wudu or ghusl.
3. A limited change caused by a clean additive does not necessarily remove suitability; dominance and substance must be assessed.
32. Summary of the Juristic Analysis
The component-based method prioritises relative proportions, whereas the property-based method examines colour, smell and taste.
The transmitted disagreement associated with Abu Yusuf and Muhammad turns on how to identify the dominant substance. Components may be clearer for similar liquids, properties for differing ones.
The shared underlying issue is where unrestricted water ceases and a transformed mixture begins.
