Lesson
1. Tanning and the Purity of Hides
After an animal dies, the use of its hide depends on whether tanning can purify it. The issue also concerns garments, leather water vessels, hair and bones.
Three rulings must be distinguished: purity of the hide, permissibility of using the purified hide, and exceptions involving certain species or human skin. These do not always rest on the same rationale.
2. Tanning Purifies the Hide
وَكُلُّ إِهَابٍ دُبِغَ فَقَدْ طَهُرَ
Translation: Every hide that has been tanned becomes pure.
Ihab denotes hide discussed under tanning rules. Dibagh is the treatment that removes residual moisture and substances causing decay.
The word kull (“every”) establishes a broad rule, followed by expressly stated exceptions.
3. What Counts as Tanning?
Tanning does not simply mean splashing water on hide or washing it briefly. It removes the moist, decaying matter that causes odour and deterioration and renders the hide preservable.
Jurists describe two forms: physical tanning and constructive tanning. The techniques differ, but the intended effect is durable preservation of the hide.
4. Physical Tanning with Tanning Agents
Physical tanning uses substances that remove moisture and matter responsible for spoilage. Examples named in the juristic discussion include alum, qaraz and pomegranate peel.
The ruling hinges on the effect achieved, not merely on a particular ingredient. Adding perfume without preserving the hide is not tanning.
5. Constructive Tanning through Drying
Constructive tanning may take place through thorough drying by sun or earth, removing the moisture responsible for decay without applying a conventional tanning agent.
What matters is that the preserving effect has actually occurred; a moment in the sun or a dusting of soil does not automatically constitute tanning.
6. A Constructively Tanned Hide Becomes Wet Again
Two transmitted views address a hide purified through constructive tanning when it becomes wet again. One says its impurity returns; the other says it remains pure.
The latter is described as the more apparent view. The question is whether subsequent moisture reverses the effective purification achieved by constructive tanning.
7. Does the Tanner’s Identity Matter?
The effectiveness of tanning, rather than the religious or social identity of the tanner, determines purification. Hence the baseline ruling does not depend upon whether the worker is Muslim, non-Muslim, adult, a child, male or female.
This illustrates the distinction between acts that require a qualified intentional agent and the legal effect of a completed material treatment.
8. Prayer and Water Use after Tanning
جَازَتِ الصَّلَاةُ فِيهِ، وَالْوُضُوءُ مِنْهُ
Translation: Prayer is permissible in it, and wudu may be performed using water from it.
Fi-hi concerns wearing or using purified leather; minhu concerns water held in a vessel made of such leather, not using leather itself instead of water.
Once the hide has been purified, it does not contaminate clothing or water by mere contact, subject to the stated exceptions.
9. The Meaning of “From It”
وَالْوُضُوءُ مِنْهُ
Translation: Performing wudu from it is permissible.
The phrase refers to a waterskin or leather vessel holding water. Water remains the substance used for wudu; the hide is simply the container.
Accordingly, purity of the leather vessel and the suitability of the water for wudu remain conceptually distinct.
10. Tanning and Lawful Slaughter
Purification of hides may arise through tanning or through valid slaughter where slaughter legally affects the animal.
A juristic principle links hides that may be purified by tanning with purification through slaughter in relevant cases. However, purity of the skin does not by itself prove that the animal’s meat is lawful to eat.
11. Dog Hide: Hanafi and Shafi‘i Disagreement
Under the Hanafi position, dog hide becomes pure through tanning. Al-Shafi‘i does not regard dog hide as purified by tanning. The disagreement concerns whether the general tanning rule includes dog hide or whether its impurity removes it from that general principle.
The Hanafi reading appeals to the general clause وَكُلُّ إِهَابٍ دُبِغَ فَقَدْ طَهُرَ
Translation: Every tanned hide becomes pure.
The expressly stated exceptions that follow refer to pig and human skin, not dog hide.
12. General Rule and Exceptions
A general term addresses a class as a whole; an exception removes a particular case from its scope. Here kullu ihab is general, while illa jild al-khinzir wa al-adami names two excluded classes.
Hanafi reasoning applies the general rule to dog hide unless a separate proof excludes it. The disagreement rests on whether the general wording should be limited further.
13. The Exceptions: Pig and Human Skin
إِلَّا جِلْدَ الْخِنْزِيرِ وَالْآدَمِيِّ
Translation: Except the skin of the pig and the human being.
Pig skin is not purified by tanning because its impurity is not treated as merely the decaying moisture within the hide.
Human skin is excluded on grounds of human dignity: treating it for use as a material is impermissible. The rationale of human sanctity must not be confused with that of pig skin.
14. Why Tanning Does Not Purify Pig Skin
Tanning removes corrupting or impure matter retained within hide. Pig skin is treated under a rule of intrinsic impurity, so tanning does not alter its underlying status.
Therefore the general wording “every hide” is not applied to pig skin: the explicit exception governs it.
15. Human Skin: A Distinct Rationale
Human dignity excludes treating human skin as an ordinary usable material even if it undergoes an apparent physical transformation through tanning. The concern is the impermissibility of such use and respect for the human person.
The fact that human and pig skins are mentioned together as exceptions does not mean the legal reasoning for the two is identical.
16. Elephant Hide: A Disagreement among the Imams
A report from Muhammad treats elephant hide analogously to pig skin, thus not purified by tanning; impurity of its bones is also reported under that view.
Abu Hanifa and Abu Yusuf are reported to allow elephant hide to become pure through tanning, with permissibility of relevant commercial use also transmitted. This is a dispute about how far the general tanning rule extends.
17. Purity Does Not Always Mean Permissible Use
Purity concerns whether an item is legally free from impurity; permissibility of use concerns whether it may legitimately be utilized. These may coincide but are not identical rulings.
The sanctity of human skin illustrates the distinction. Conversely, an otherwise permitted hide purified by tanning may be used as clothing or a waterskin, absent a separate prohibition.
18. The Hair and Bones of Carrion
وَشَعْرُ الْمَيْتَةِ وَعَظْمُهَا طَاهِرٌ
Translation: The hair and bones of a dead animal are pure.
This ruling is separate from the tanning of carrion hide. Tanning is the issue for the hide, while hair and bone are treated under a different juristic rationale.
The general principle is subject to the stated exception concerning pigs and to distinctions such as cut hair versus hair pulled from its roots.
19. Principle: Parts Not Affected by the Animal’s Death
كُلُّ مَا لَا تَحُلُّهُ الْحَيَاةُ لَا يَحُلُّهُ الْمَوْتُ
Translation: What life does not permeate is not affected in the same way by death.
Hanafi reasoning uses this principle for the purity of hair, bones and certain hard parts. Impurity arising from death is not automatically assigned to every part lacking that living, blood-bearing quality.
The rule does not nullify separate restrictions such as the intrinsic impurity attributed to pigs.
20. Hair, Wool, Feathers and Hard Parts
Examples of hard or non-blood-bearing parts include hair, wool, down, feathers, horns, hooves and similar hard parts. Their continued purity after death is discussed under the general Hanafi rationale.
Application still depends on the animal and how the material was detached, particularly if hair has been pulled out together with moist skin tissue.
21. Cut Hair versus Plucked Hair
Cut hair or hair detached without impure moisture is treated as pure. Hair pulled from the roots together with moist, impure tissue is treated differently because of the material attached to it.
The distinction lies between the hair substance and accompanying impure tissue; the general purity statement should not be extended indiscriminately to every attached root or wet fragment.
22. Pig Bristles and an Exceptional Necessity Discussion
Pig bristles do not simply follow the general ruling of other animal hair. A narrow necessity-based concession is reported for specific applications where an alternative was assumed unavailable.
Disapproval of that use is also reported from Abu Yusuf, with non-permissibility of their trade transmitted. Such an exceptional necessity discussion does not establish general purity or unrestricted commerce in pig bristles.
23. Shafi‘i Position on Carrion Hair and Bones
Under the Hanafi position, carrion hair and bones are pure under specified conditions. Al-Shafi‘i classifies the hair and bones of carrion as impure.
The disagreement concerns the application of death-related impurity: the Shafi‘i view does not separate these parts as the Hanafi reasoning does through the principle that life does not permeate them.
24. Maliki Position: Hair and Bone Differ
Malik treats carrion hair as pure but its bones as impure. The Maliki view therefore differs from both the broader Hanafi purity view and the Shafi‘i impurity view.
In summary: Hanafi—both pure subject to qualifications; Shafi‘i—both impure; Maliki—hair pure, bones impure. The disagreement turns on the legal characterization of the different parts.
25. Human Hair, Nails and Bones
Further transmitted opinions address human hair, nails and bones, including more than one report from Muhammad on their impurity.
The intrinsic purity of a part and the permissibility of using parts of the human body must be treated separately. Human dignity prevents an automatic inference from purity to permission of use.
26. An Egg Released from a Dead Hen
The ruling for an egg emerging from a dead hen is also discussed. The Hanafi position treats the egg as pure and usable whether its shell has fully hardened or not.
A Shafi‘i distinction is transmitted between a hard-shelled egg, which is pure, and a soft-shelled egg, whose status differs. The underlying issue involves the egg’s separate nature and the condition of its protective covering.
27. Tanning Does Not Purify Meat or Fat
The tanning ruling applies to hide. It does not imply that carrion meat or fat can be purified by tanning; those tissues have separate legal statuses.
The term ihab identifies the subject of the ruling. It should not be generalized to every substance in an animal carcass.
28. Practical Cases in Purified Leather
Case 1: An ordinary hide is effectively tanned and fashioned into a waterskin; under the core Hanafi ruling it may hold clean water for wudu.
Case 2: Dog hide is effectively tanned; the Hanafi and Shafi‘i rulings differ on its purity.
Case 3: Pig skin is tanned; the explicit exception means it does not become pure. Human skin also has a separate prohibition grounded in dignity.
29. Practical Cases in Hair and Bones
Case 1: Wool is cut from a dead sheep without attached impure tissue; it is pure under the Hanafi principle.
Case 2: Hair is plucked with moist impure tissue remaining at the root, triggering a separate impurity issue.
Case 3: The ruling on a bone from carrion differs among the Hanafi, Shafi‘i and Maliki schools; the word “carrion” alone does not settle the disagreement.
30. Comparative Summary: Hide, Hair and Bone
Tanned hide: Pure in the Hanafi principle subject to the pig and human exceptions; dog hide is disputed with the Shafi‘i school.
Carrion hair: Pure with qualifications in the Hanafi view, impure in the Shafi‘i view, pure in the Maliki view.
Carrion bone: Pure in the Hanafi view, impure in the Shafi‘i and Maliki views.
These positions rest on different understandings of the substance, the effect of tanning and whether death transfers impurity to a particular part.
31. Summary: Purity, Exceptions and Rationale
The general rule establishes purification of hides through tanning and thereby permits ordinary uses such as garments or leather water containers. Pig skin and human skin are excluded, but for distinct legal reasons.
Carrion hair and bones are governed by a separate Hanafi principle, with Shafi‘i and Maliki disagreements. The details also involve physical versus constructive tanning, dog and elephant hides and contact with impure tissue at hair roots.
