Lesson

1. Well Purification: Defining a Small Well

• Juristic Framework: In Hanafi jurisprudence, the rulings governing well contamination and purification are strictly determined by the well's physical dimensions. • Defining a Small Well: Any well whose water surface area is less than ten-by-ten cubits (Mā dūna 'ashrin fī 'ashrin / approx. 5x5 meters). • The Ruling: The water inside a small well is legally classified as stagnant (Rākid). The fall of any physical impurity contaminates the entire volume of water, unlike large flowing wells.

2. Contamination by Non-Living Filth

Source text تَنْزَحُ الْبِئْرُ الصَّغِيرَةُ بِوُقُوعِ نَجَاسَةٍ وَإِنْ قَلَّتْ كَقَطْرَةِ دَمٍ أَوْ خَمْرٍ • The Principle: If any non-living, physical impurity (Najasah) falls into a small well, no matter how minute the quantity: • Example: A single drop of blood, a droplet of urine, semen, or alcohol. • The Ruling: This minor contamination corrupts the entire well water, necessitating the complete drainage (Tanzīh kullihā) of the well to purify it.

3. Pig Falling Into the Well

Source text وَبِوُقُوعِ خِنْزِيرٍ وَلَوْ خَرَجَ حَيًّا وَلَمْ يُصِبْ فَمُهُ الْمَاءَ • The Scenario: If a pig falls into a small well: • The Ruling: The entire well water becomes impure, and complete drainage is mandatory to purify the well. • Even if the pig is extracted alive and its mouth did not touch the water, the well is contaminated. Why? • Juristic Reason: Because a pig is inherently impure (Najis al-'Ayn); its bristles, skin, and body contaminate water immediately upon contact.

4. Death of Large Animals (Dog, Sheep, Human)

Source text وَبِمَوْتِ كَلْبٍ أَوْ شَاةٍ أَوْ آدَمِيٍّ فِيهَا • The Scenario: If a large living creature falls into the well and dies inside (and is extracted before swelling): • Example: A dog, a sheep/goat (Shāh), or a human. • The Ruling: The death of a large animal contaminates the entire volume of water, and complete drainage of the well is obligatory. • A dog's saliva is impure, and the death of a sheep or an unwashed human introduces bodily impurities that contaminate the well.

5. Swelling or Disintegration of Any Carcass

Source text وَبِانْتِفَاخِ حَيَوَانٍ وَلَوْ صَغِيرًا • The Scenario: If an animal dies inside the well and swells (Antafakha) or disintegrates/decays (Tafassakha) inside the water: • The Ruling: The entire well water becomes impure, and complete drainage is obligatory. • Regardless of how small the animal may be (even a small mouse, lizard, or sparrow). • Reason: The swelling or decay of a carcass releases internal putrid bodily fluids and blood into the water, severely contaminating the entire well.

6. When Complete Drainage is Physically Impossible

Source text وَمِائَتَا دَلْوٍ لَوْ لَمْ يُمْكِنْ نَزْحُهَا • The Scenario: If a well is situated on a spring or rock such that water keeps replenishing continuously, making complete drainage physically impossible: • The Ruling: The authenticated Hanafi verdict (Ahl al-Tarjih) establishes that draining two hundred (200) buckets of water is legally sufficient to purify the well. • Bucket Standard: The bucket used must be the custom bucket of that specific well. If no custom bucket exists, a standard medium-sized bucket (Dalu al-Mutawassit) is utilized.

Practice questions

Question 1

What is the legal definition of a "small well" (al-Bī'r al-Saghīrah) in Hanafi Fiqh?

  • A well containing less than 100 buckets.
  • A stagnant body of water whose surface area is less than ten cubits by ten cubits.
  • A well deeper than 10 meters.
  • A well connected directly to the Nile river.

Question 2

If a single drop of wine or blood falls into a small well, the entire well becomes contaminated, requiring complete drainage.

Question 3

What is the ruling if a pig falls into a small well and is extracted alive without its mouth touching the water?

  • The well remains completely pure because the pig exited alive.
  • The well must be completely drained because the pig is inherently impure (Najis al-'Ayn).
  • Draining only 20 buckets is sufficient.
  • Only the edge of the well must be wiped.

Question 4

If a human or a sheep dies in a small well, the well must be completely drained, even if the carcass has not swollen or disintegrated.

Question 5

If a small animal (such as a mouse) dies in a small well and swells or decays, what is the required purification?

  • Draining only 20 buckets.
  • Complete drainage of the well.
  • Washing the carcass and returning it to the well.
  • No purification is required because the animal is small.

Question 6

If a well is connected to an active spring making complete drainage physically impossible, the requirement for purification is dropped entirely and the water is ruled pure.

Question 7

Match the animal falling scenarios with their correct well drainage requirements:

Question 8

When complete drainage is impossible, how is the size of the bucket determined to count the 200 buckets?

  • The custom bucket of that specific well, or a standard medium bucket if none exists.
  • The largest bucket available in the city.
  • Exactly 1 liter per bucket.
  • Any cup or household vessel.
