Istinja: Methods, Preference and Juristic Differences

1. Legal Status of Istinja

وَالِاسْتِنْجَاءُ سُنَّةٌ
Translation: Istinja is a sunnah.

Istinja means cleansing the exit after urination or defecation. It concerns removal of physical impurity rather than wudu or ghusl themselves.

The statement that istinja is a sunnah concerns ordinary cleaning at the exit. A separate rule applies if impurity spreads beyond its normal location.

2. Istinja and Istibra

Istinja removes filth from the exit. Istibra means ensuring that remaining drops of urine have ceased.

They address different issues: washing the exit does not make an ongoing discharge stop, and cessation of urine does not itself remove filth already present at the exit.

3. Stone, Earth Clod and Equivalents

يُجْزِئُ فِيهِ الْحَجَرُ وَالْمَدَرُ وَمَا قَامَ مَقَامَهُمَا
Translation: A stone, a dry lump of earth, and comparable cleansing materials suffice.

Hajar means stone, and madar a dry clod of earth. The material must be clean and capable of actually removing filth.

The phrase “what serves the same purpose” concerns an equivalent cleansing function, not the name of the material alone.

4. Conditions for an Equivalent Cleansing Material

A clean, suitable material capable of cleansing the exit may fall under the rule of stone and dry earth, unless it is specifically prohibited.

The objective is inqa’, actual cleansing. Bones, dung and food are exceptions to the general allowance.

5. Inqa’: Actual Cleansing

يَمْسَحُهُ حَتَّى يُنْقِيَهُ
Translation: He wipes with it until it cleans the area.

The words “until it cleans” tie completion to removal of filth. Merely passing a stone over the surface does not suffice while impurity remains.

This dry-cleansing permission concerns the ordinary exit region; a wider spread of impurity is treated separately.

6. Cleanliness versus Number of Passes

Inqa’ means removing the material filth to the degree required for dry cleansing, not simply reducing its appearance.

If one or two passes do not clean the area, further wiping is needed. Conversely, once cleansing is achieved, the Hanafi ruling does not require a further fixed number merely for its own sake.

7. Is a Fixed Number Required?

وَلَيْسَ فِيهِ عَدَدٌ مَسْنُونٌ
Translation: No fixed number is prescribed for it.

The governing criterion in this view is effective cleansing, not a predetermined count.

Al-Shafi‘i, however, requires a minimum of three wipes in dry cleansing even when the area appears clean earlier.

8. Al-Shafi‘i: At Least Three Wipes

Al-Shafi‘i requires at least three cleansing wipes, whether using three separate stones or three clean edges of one stone.

His evidence is the Prophetic instruction:
فَلْيَسْتَنْجِ بِثَلَاثَةِ أَحْجَارٍ
Translation: Let him cleanse with three stones.

The imperative is understood to establish a minimum of three wipes, even where cleansing appears complete earlier.

9. Hanafi View: Cleansing Is Decisive

In the Hanafi view, effective cleansing (inqa’) is decisive and three wipes are not a universal validity requirement.

The report says:
مَنْ اسْتَجْمَرَ فَلْيُوتِرْ
Translation: Whoever cleanses with stones should use an odd number.

It also says:
وَمَنْ لَا فَلَا حَرَجَ
Translation: And whoever does not, there is no blame.

Read together, these encourage an odd count without making it a condition of validity. If filth remains, further cleansing is still required.

10. Two Wipes Achieved Cleansing: Applying the Dispute

A person cleanses completely with two stones.

Hanafi view: the cleansing is sufficient; an odd count remains desirable.

Shafi‘i view: at least one more clean wipe is needed to complete the minimum count.

If impurity still remains after the third wipe, further cleaning is needed under both approaches.

11. Washing with Water Is Preferable

وَغَسْلُهُ بِالْمَاءِ أَفْضَلُ
Translation: Washing it with water is preferable.

Water better removes the substance and lingering traces of impurity, and is therefore preferred.

Permission to cleanse with stones and the superiority of washing with water are different rulings: one establishes sufficiency, the other preference.

12. Why Water Is Preferred: Quranic Basis

The Quran states:
فِيهِ رِجَالٌ يُحِبُّونَ أَنْ يَتَطَهَّرُوا
Translation: “In it are people who love to purify themselves.”

The verse is used in support of thorough cleanliness with water. Preference for water does not cancel the legal sufficiency of stones in their valid circumstances.

13. Comparing Dry Cleansing and Washing

Dry cleansing with stone or an equivalent suffices at the normal exit if the area is actually cleansed.

Washing with water is superior as it can remove traces that dry rubbing may leave behind.

If impurity spreads beyond the exit, the general dry-cleansing permission becomes restricted.

14. Impurity Spreading Beyond the Exit

وَإِنْ تَجَاوَزَتِ النَّجَاسَةُ مَخْرَجَهَا لَمْ يَجُزْ فِيهِ إِلَّا الْمَاءُ أَوِ الْمَائِعُ
Translation: If impurity extends beyond its normal exit, cleansing there is valid only with water or an appropriate liquid.

Spread beyond the exit means that impurity reaches skin outside the normal area covered by dry-cleansing concession. Removal of such impurity is governed by the rules of cleaning the body.

An acceptable liquid here means a pure liquid that effectively removes impurity, as discussed previously.

15. Ordinary Exit versus Spread

The ordinary exit can be dry-cleansed under its special allowance. If impurity reaches surrounding skin beyond that region, the excess must be evaluated under broader rules for removing bodily filth.

A limited trace at the exit and impurity spread onto adjacent areas are therefore two different cases.

16. Abu Hanifah and Abu Yusuf: The Extent of Spread

Abu Hanifah and Abu Yusuf require washing when impurity beyond the exit exceeds the dirham threshold.

If the excess is below that threshold, the excused-quantity rule is relevant; in their calculation, impurity remaining at the normal exit is not automatically added to the excess to exceed the limit.

This follows a distinction between the special dry-cleansing concession and the tolerated quantity of bodily filth.

17. Muhammad: The Rule When Filth Spreads

Muhammad does not consider stones sufficient once filth extends beyond the exit; washing with water or an acceptable pure liquid is required even when the excess alone is less than a dirham.

His assessment of the amount may also take impurity at the exit together with the spread outside it.

Thus, the two senior pupils of Abu Hanifah differ on some details of spread beyond the exit.

18. Three Cases of Spread

Case 1: Filth remains within the ordinary exit area and dry cleansing achieves cleanliness: stones can suffice.

Case 2: Excess beyond the exit exceeds a dirham: effective washing with water or a qualifying liquid is required.

Case 3: Excess is below that threshold: Abu Hanifah and Abu Yusuf differ in detail from Muhammad; stones should not be declared universally sufficient.

19. Water or Cleansing Liquid: Scope of the Rule

The permission to remove physical impurity with certain pure liquids other than water is itself disputed among Hanafi jurists. Abu Hanifah and Abu Yusuf allow a qualifying liquid that removes the actual filth, whereas Muhammad takes a more restrictive view.

Therefore, “or a liquid” does not license every liquid without conditions, nor does it mean one may perform wudu with it. Removing bodily filth and removing hadath are separate rulings.

20. Four Prohibitions in Istinja

وَلَا يَسْتَنْجِي بِعَظْمٍ، وَلَا رَوْثٍ، وَلَا بِطَعَامٍ، وَلَا بِيَمِينِهِ
Translation: One must not cleanse with a bone, dung, food, or the right hand.

The four prohibitions have distinct grounds: bones and dung are specifically prohibited in hadith; food is to be respected rather than used for cleansing; and the right hand is kept away from this act.

These exclusions qualify the earlier general permission for stones and equivalent materials.

21. Why Bones and Dung Are Prohibited

The prohibition on using bones and dung is established by hadith. Reports connect these items to provision for jinn, explaining their exclusion from cleansing materials.

Whether a prohibited item might physically remove filth and whether it is permitted to be used are separate legal questions; the ruling here prohibits its use.

22. Why Food May Not Be Used

Food is meant for nourishment. Using it for cleansing after excretion is wasteful and disrespectful.

The capability of an item to wipe a surface is therefore not the only criterion: its proper lawful use must also be respected. Food is excluded from otherwise comparable cleansing materials.

23. The Right-Hand Prohibition

Use of the right hand for istinja is prohibited. The relevant hadith wording is:
وَلَا يَسْتَنْجِي بِيَمِينِهِ
Translation: He should not cleanse with his right hand.

The left hand is used for cleaning the soiled area. This concerns the specific cleansing act, not a general prohibition on handling a water vessel with the right hand.

24. Sunnah and Preferred Method: A Distinction

Sunnah: describes the legal status of ordinary istinja.

Sufficiency of stones: permits effective dry cleansing.

Preference for water: ranks water above stones where both methods are valid.

Spread of filth: triggers a separate requirement for washing under the applicable conditions.

These four propositions operate at different legal levels.

25. Number, Cleansing and Permitted Materials

Number of wipes: no fixed count for Hanafis; at least 3 for al-Shafi‘i.

Required outcome: actual cleansing.

Permitted means: stones, dry earth, qualifying equivalents; water is preferable.

Forbidden means: bones, dung, food, or using the right hand.

Limit: filth spread beyond the exit is treated separately.

26. Four Legal Case Studies

1. Two stones achieve cleansing at the normal exit: sufficient in the Hanafi view, but al-Shafi‘i still requires the minimum three wipes.

2. Dry cleansing succeeds and the area is then washed with water: the more complete, preferred method.

3. Filth extends beyond the exit: the rule depends on the degree of spread and the juristic position on washing.

4. Food or bone is used for dry cleansing: the implement itself is prohibited even if some filth is physically removed.
