Argument Without New Proof: Absence of a Cause and Presumption of Continuity

1. Argument without a new proof: the issue

فصل في الاحتجاج بلا دليل
A chapter on argumentation without an independent affirmative proof.

الاحتجاج بلا دليل أنواع؛ منها
There are several forms of argumentation without such a proof; the following are among them.

One must distinguish failure to establish a ruling from positive proof that the ruling cannot exist. A party may show that an opponent has not proved a claim without establishing its definitive opposite.

Two methods are considered: inferring the absence of a ruling from the absence of a specified legal cause, and preserving an already established state when no proof of change appears. Their reach is not the same.

2. Inferring absence of a ruling from an absent cause

الاستدلال بعدم العلة على عدم الحكم
To argue that a ruling is absent because its cause is absent.

For example, someone may say that a ruling does not apply because the reason ordinarily cited for it is missing. The crucial question is whether this is the only legally recognized cause of that ruling.

If more than one cause can establish the ruling, absence of one cause does not eliminate every possible basis. Treating the failure of a particular cause as proof of universal absence is a logical and jurisprudential error.

3. When the cause is genuinely exclusive

إلا إذا كانت علة الحكم منحصرة في معنى
Unless the cause of the ruling is confined to one particular factor.

This exception is decisive. If reliable evidence establishes that a specified legal consequence has one exclusive sufficient cause and no alternative cause applies, absence of that factor can support absence of the consequence.

But “this cause is missing here” and “this is the only possible cause” are different propositions. The former identifies a missing factor; the latter requires proof of exclusivity. Without that second premise the negative conclusion does not follow.

4. The example of vomiting and ablution

القيء غير ناقض؛ لأنه لم يخرج من السبيلين
Vomiting does not invalidate ablution, because it did not exit through the two specified passages.

This argument uses one recognized basis for invalidation to deny the possibility of another. Its defect is that exit through the two passages being a cause does not prove that every possible cause of invalidation must be confined to it.

If independent evidence establishes a rule about vomiting, merely saying it does not originate from the two passages is insufficient to reject that evidence. This concerns a particular argument in Hanafi jurisprudence, not a claim of agreement among all schools about vomiting.

5. Kinship and emancipation: more than one relevant relation

والأخ لا يعتق على الأخ؛ لأنه لا ولاد بينهما
A brother is not emancipated by his brother's ownership, since the relation of parenthood is absent between them.

The lack of direct parenthood would be decisive only if that relationship were proved to be the exclusive cause of the relevant emancipation rule. Absence of parenthood alone cannot settle the legal significance of all other relevant kinship relations.

The point of this classical example is not that all kinship cases must have the same result. It is to test an inference that equates absence of one specific cause with absence of every possible legal foundation.

6. The minor's partner in a homicide case

أَيجب القصاص على شريك الصبي؟ قال: لا؛ لأن الصبي رفع عنه القلم
Is retaliation required against the person who participated with a minor? The answer given is no, because the minor is not legally accountable.

This historical legal discussion concerns the link between joint participation and liability for retaliation. The minor's lack of legal responsibility alone does not automatically supply the full reasoning for the other participant; the conditions of a jointly attributed offense must also be explained.

The teaching point is to identify the missing inferential link: why does a limitation affecting one participant change the consequence for another?

7. The comparison with a father reveals the missing premise

فوجب أن يجب على شريك الأب؛ لأن الأب لم يرفع عنه القلم
Then retaliation should be required against the father's partner, because the father is not exempt from legal accountability.

The response exposes the earlier inference's weakness. If nonliability of the minor's partner is explained solely through the minor's exemption, that explanation cannot by itself settle the case involving a legally accountable father, whose situation has its own specific legal treatment.

A particular reason for the nonapplication of a ruling does not finish the legal analysis. One must identify the evidence for the liability rule, and then the relevant exemption or impediment in each distinct case.

8. What the absence-of-cause argument actually proves

عدم خصوص تلك العلة لا يستلزم عدم الحكم
The absence of this particular cause does not necessitate absence of the ruling.

One cause may fail while another legally sufficient cause remains. For example, the absence of a familiar kind of kinship or responsibility does not automatically remove all other possible bases for a legal consequence.

The correct sequence is to identify the ruling's proof, list relevant causes, and then establish whether the cause is exclusive. Without exclusivity one may say “this cause does not establish the ruling,” but not yet “the ruling has no possible basis.”

9. Usurpation and the child of an enslaved woman

ولد المغصوبة ليس بمضمون؛ لأنه ليس بمغصوب
The child of an unlawfully seized enslaved woman is not covered by liability for usurpation in that particular capacity, since the child was not itself seized.

In this historical example, the specific cause of liability for usurpation is unlawful dispossession of the owner. If that same act is not independently established in relation to the child, the conditions of this particular form of liability change.

This illustrates the opposite case: when the ruling is truly tied to a defined exclusive legal act, its absence can matter. It does not imply that every other possible responsibility has also been ruled out.

10. Witnesses withdrawing testimony and retaliation

ولا قصاص على الشاهد في مسألة شهود القصاص إذا رجعوا؛ لأنه ليس بقتال
When witnesses withdraw testimony in a retaliation case, the witness is not himself subjected to retaliation, for he did not commit the killing.

Here the specific legal consequence of retaliation is tied to the attribution of the relevant killing. Other possible effects of testimony or its withdrawal are separate matters; giving testimony is not identical to performing the killing.

As in the usurpation case, the point is to distinguish the cause required for a specified ruling from all possible consequences of the wider event.

11. The meaning of istishab al-hal

التمسك باستصحاب الحال تمسك بعدم الدليل
Reliance on the continued previous state is reliance on the absence of evidence establishing change.

Under istishab al-hal, a status is first established through a valid basis; no sufficient proof of its termination or alteration later appears. The existing status is therefore presumed to continue for a limited legal purpose.

For example, a person's life was previously established and no reliable evidence of death exists. The presumption may protect that earlier status, but it does not automatically establish every new entitlement or obligation.

12. Defending an existing state versus creating a new claim

فيصلح للدفع دون الإلزام
It is fit for rebuttal or defense, not by itself for imposing a new entitlement or obligation.

Defensive use (dafʿ) preserves an already established situation against an unproved new claim. Affirmative imposition (ilzam) establishes a new right, obligation, or financial claim against another party.

These are not interchangeable. “Do not overturn what was established without proof” is a limited principle; “every new entitlement follows from that prior status” is a stronger claim and requires independent support.

13. A comparison of the two uses of istishab

FeatureDefenseNew impositionPurposeProtect an established rightEstablish a new entitlementForce of istishabSupports continuityInsufficient on its ownExampleProtecting missing person's estateClaiming a new inheritance for the missing person

The same previously established fact may feature in both claims. Yet the type of claim determines the legal force of the presumption. Ask in each case whether the party seeks to protect an existing position or acquire a new entitlement.

14. A missing person and protection of existing property

فيصلح للدفع دون الإلزام
The presumption preserves an earlier position but cannot alone impose a new claim.

A missing person (mafqud) was previously known to be alive, but is now neither reliably confirmed alive nor dead. In the absence of adequate evidence of death, his existing estate is not distributed merely on a possibility that he has died.

Here istishab serves defense: it protects established ownership against an unproved alteration. It does not yet create a new entitlement for the missing person.

15. Why the missing person does not automatically gain a new inheritance

فإنه لا يستحق ميراث غيره
A missing person does not, solely through istishab, become entitled to inherit from someone else.

If a relative dies, the missing person's survival at that relevant time matters for a new inheritance claim. Presuming the prior life continues does not, by itself, establish such a new claim against other heirs.

Thus the same apparent proposition—“treat the missing person as alive”—has two different uses: protecting existing property and creating a fresh inheritance right. The first is defensive; the second requires independent proof.

16. Unknown parentage and the presumption against enslavement

مجهول النسب لو ادعى عليه أحد رقًّا ثم جنى عليه جناية لا يجب عليه أرش الحر
If someone claims ownership of a person of unknown parentage and the person later suffers an injury, the specific compensation owed for an established free person does not follow from mere presumption of the earlier state.

This historical example separates two claims: rejecting an unproved assertion of enslavement, and affirmatively imposing the specified compensation for injury to a free person upon another party. Rejecting the first does not automatically prove the second.

The example serves to explain a classical legal distinction and is not modern practical guidance or an endorsement of slavery.

17. Presuming a known menstrual pattern

إذا زاد الدم على العشرة في الحيض، وللمرأة عادة معروفة، ردّت إلى أيام عادتها
If bleeding extends beyond ten days and the woman has an established habit, the ruling refers back to her customary days.

The previously known pattern matters in applying the Hanafi limits distinguishing menstruation from irregular bleeding. With bleeding beyond the upper limit, the earlier habit helps classify the relevant days.

This is a jurisprudential example, not simply a medical observation. Its legal analysis depends on the established habit, observed duration, and the school’s applicable time limit; it is not stated as an identical rule across all legal schools.

18. Bleeding below ten days: effect of uncertainty

إذا ابتدأت مع البلوغ مستحاضة فحيضها عشرة أيام
When irregular bleeding accompanies the onset of puberty, the discussion assigns ten days as menstruation in this specific case.

The analysis differs from the previous example. Where legal status is uncertain and no change has been established, an earlier status is not overturned without proof; but an independently established time limit must be followed where applicable.

The text distinguishes bleeding below and above ten days. This shows why presumption cannot operate without regard to a recognized legal limit or direct evidence.

19. Istishab cannot defeat an established legal proof

والحيض لا يرتفع إلا بدليل
The legal status of menstruation is not treated as ended without proof.

This is not an unlimited principle. An established status requires evidence of change, but where a specific legal limit or other decisive evidence governs the duration, the presumption yields to that proof.

Istishab is used when change has not been established. It is not an independent competing authority that overrides direct scripture or other recognized evidence.

20. The question of khums on ambergris

قد روي عن أبي حنيفة أنه قال: لا خمس في العنبر
It is reported from Abu Hanifah that no khums is due on ambergris.

Ambergris is associated with the sea. The legal question is whether the rule of spoils, minerals, or some other category governs the levy. To decide the inference one must identify the legal cause relevant to khums in the proposed comparison.

Merely saying that “ambergris is like fish” is insufficient unless a legally relevant shared cause is established for the particular rule at issue.

21. Ambergris and fish: examining the analogy

إنه كالسمك؛ فقال: فما بال السمك لا خمس فيه؟ قال: لأنه كالماء ولا خمس فيه
Ambergris was likened to fish. When asked why fish bear no khums, the reply likened them to water, on which no khums is due.

The exchange separates surface resemblance from a valid legal cause. Calling one thing like fish and fish like water cannot establish the ruling unless the attribute on which the law actually depends is identified.

A proper analogy requires separate examination of the original case, the new case, the ruling and a legally relevant cause common to them. Mere comparison of physical characteristics is inadequate.

22. The original legal basis in the ambergris discussion

لم يشرع الخمس إلا في الغنيمة، والعنبر ليس من الغنائم
Khums is legislated in relation to spoils, while ambergris is not classified as such spoils.

This reasoning emphasizes identifying the legally relevant category instead of relying simply on “water has no khums, so nothing resembling water has khums.” If the levy is tied to a particular class of property, the question is whether the disputed item belongs to that class.

The conclusion is therefore discussed in terms of the levy’s basis, its subject matter, and legal evidence rather than casual physical similarity.

23. The limits of claiming no evidence and abandoning analogy

ولما لم يرد النص على خلاف هذا القياس لم يترك
Since no text was reported contradicting this analogy, it was not discarded.

The closing methodological caution distinguishes not finding an explicit text about every detail from finding no text contrary to an otherwise sound analogy. A valid qiyas is not rejected merely because each new application lacks its own verbal text.

Yet the analogy must first establish a legally sound cause. It is mistaken both to dismiss every inference as unsupported and to impose new consequences merely on an unproved assertion.

24. The two methods brought together

MethodLegitimate useLimitAbsence of causeNegation when the cause is exclusiveFails if other causes may applyIstishabDefensive protection of an established stateDoes not alone create new rights

Both methods require fidelity to the actual reach of the evidence. Without exclusivity one cannot infer universal absence of a ruling; without fresh evidence one cannot transform a prior state into unlimited affirmative claims.

The core skill is not merely naming doctrines but assessing exactly what conclusion a given premise can support.

25. Connection to qiyas and completion of the text

والله تعالى أعلم بالصواب
God knows best what is correct.

Deriving legal rulings requires more than reading the surface of a single verse or report: verbal indications, the strength of evidence, consensus, causal analysis, analogy, and the limits of proof interact.

Conclusion: A legal inference should claim no more than its sound premises establish. Absence of a cause negates a ruling only where the cause is exclusive. Istishab can defend an existing state but does not automatically establish a new entitlement.

The final principle is to identify the reach of each proof, examine the cause, and distinguish protection of an established status from creation of a fresh claim.
