Water Mixtures: When Does Another Substance Dominate?

Read the bilingual lesson for Water Mixtures: When Does Another Substance Dominate? and test your understanding with a focused quiz.

Lesson

1. The Principle of Dominance in Water Mixtures

• When a pure substance mixes with Absolute Water, the key question is whether the liquid still retains the legal character of water or whether the additive has become dominant.
• The text calls this principle dominance (al-Ghalabah).
• The test for dominance is different for:
1. solid substances,
2. liquids with visible qualities, and
3. liquids whose qualities do not distinguish them from water.

2. When a Solid Substance Mixes with Water

Source text
وَالْغَلَبَةُ فِي مُخَالَطَةِ الْجَامِدَاتِ بِإِخْرَاجِ الْمَاءِ عَنْ رِقَّتِهِ وَسَيَلَانِهِ

• With a pure solid additive, dominance is established when the water loses its normal thinness and flowability.
• If the water remains thin and flows normally, a change in color, taste, or smell caused by a solid does not by itself prevent Wudu.
• The text gives examples such as saffron, fruit, and tree leaves.
• This is a question of whether the water remains purifying; mixing a pure substance does not itself make the water physically impure.

3. Liquids with Their Own Color, Taste, or Smell

Source text
وَالْغَلَبَةُ فِي الْمَائِعَاتِ بِظُهُورِ وَصْفٍ وَاحِدٍ مِنْ مَائِعٍ لَهُ وَصْفَانِ فَقَطْ...

• If the added liquid has two distinct qualities, dominance is established when one of those qualities appears in the water.
◦ Example: milk is treated here as having color and taste; if either appears, milk is dominant.
• If the added liquid has three qualities, dominance is established when two of them appear.
◦ Example: vinegar has color, taste, and smell; one appearing is not enough, but two appearing establish dominance.

4. Liquids Without Distinguishing Qualities: Judge by Weight

Source text
وَالْغَلَبَةُ فِي الْمَائِعِ الَّذِي لَا وَصْفَ لَهُ كَالْمَاءِ الْمُسْتَعْمَلِ... تَكُونُ بِالْوَزْنِ

• Used water does not have a different color, taste, or smell by which it can be distinguished from Absolute Water. Its dominance is therefore judged by weight.
• 2 ratls of Used Water + 1 ratl of Absolute Water → Used Water dominates → not valid for Wudu.
• 1 ratl of Used Water + 2 ratls of Absolute Water → Absolute Water dominates → valid for Wudu.
• Ratl is the traditional unit used by the text; the point here is the relative proportion, not conversion to a modern unit.

5. What If the Two Amounts Are Equal?

• The text gives the rule when one type clearly outweighs the other.
• For the equal-weight case, the supplied commentary states that no explicit ruling is mentioned in Zahir al-Riwayah.
• It then reports the precautionary ruling of the Hanafi mashayikh: when the two are equal, Wudu with that mixture is not treated as valid.
• This does not mean the mixture has become physically impure; the issue is its capacity to purify for Wudu.

Practice questions

Question 1

Dry saffron changes the color, taste, and smell of water, but the water remains thin and flows normally. What is the ruling for Wudu?

Wudu is completely invalid because all three qualities changed.
Wudu is fully valid because thinness and flowability are preserved.
Wudu is valid only if Tayammum is performed with it.
The water is classified as impure (Najis).

Question 2

For a liquid with no distinguishing color, taste, or smell—such as Used Water—dominance in a mixture is judged by weight.

Question 3

Match each proportion of Used Water and Absolute Water with its ruling for Wudu.

Question 4

A liquid such as milk is treated here as having two qualities. How many of those qualities must appear in the water for the milk to be dominant?

Both qualities must appear.
Only one quality must appear.
No qualities need to appear, weight is used.
One quality appears, but only if cooked.

Question 5

If vinegar mixes with water and only one of its three qualities appears, vinegar is already dominant and Wudu is invalid.

Question 6

If Used Water and Absolute Water are mixed in exactly equal weights, what precautionary ruling is reported in the supplied commentary?

Absolute Water is treated as dominant, so Wudu is valid.
As a precaution, Wudu with this mixture is not treated as valid.
Dominance is decided only by color, taste, and smell; weight is ignored.
When both are equal, the mixture automatically becomes Absolute Water.

Question 7

Match each additive with the method used to determine whether it dominates the water.

Question 8

If 2 ratls of Absolute Water are mixed with 1 ratl of Used Water, the mixture remains valid for Wudu.
