Legal Impediments: Formation, Completion, Commencement and Continuation

1. The function of an impediment

فصل في الموانع
Chapter on legal impediments.

An impediment (māniʿ) is a legally relevant factor that can block the formation or completion of a legal cause, the initial operation of a ruling, or the continuation of a ruling already established. It must be studied alongside the distinction between causes, operative legal grounds and conditions.

An attempted transaction may never become operative; by contrast an established contractual ruling may later become defeasible through an option of rescission. These cannot be treated as the same effect: in the first case there is no initial establishment, while in the second continuation is at issue.

2. The fourfold classification

الموانع أربعة أقسام
Impediments fall into four categories.

CategoryWhat is blocked?Formation of the causeIts operative constitutionCompletion of the causeThe remaining elements needed for full operationCommencement of the rulingThe ruling taking effect initiallyContinuation of the rulingPersistence of an established effect

A jurist must determine which stage is interrupted. Simply observing that a legal effect fails to appear does not explain whether the cause was never constituted, remained incomplete, was barred from operating, or ceased to retain its effect.

3. Cause, legal ground and impediment

A cause or operative legal ground supplies the basis to which a legal ruling is attached; an impediment prevents that basis or its result from operating in a specified situation.

For zakat, the qualifying property and the completion of a year are related to obligation. If the qualifying basis disappears during the year, the issue is completion of the operative cause rather than merely delayed payment. By contrast, a buyer's option upon seeing the goods concerns whether an already concluded sale remains binding.

Not every impediment should be collapsed into the absence of a condition. The fourfold classification identifies different legal effects and stages.

4. First: blocking formation of the cause

مانع يمنع انعقاد العلة
An impediment preventing constitution of the legal cause.

At this stage, the attempted act never becomes an operative legal ground. Words alone cannot produce a legal result unless the subject matter is legally capable of receiving that transaction.

An incomplete cause can have an initially valid basis awaiting completion; a nonconstituted cause lacks the foundational legal capacity to operate. Subsequent satisfaction of some incidental requirement does not automatically validate a transaction that never validly arose.

5. Sale involving a free person, carrion or blood

نظير الأول: بيع الحر، والميتة، والدم
The first category is illustrated by the purported sale of a free human being, carrion or blood.

Under the classical legal treatment discussed here, these are not valid sale subjects for the contemplated transfer of proprietary title. The purported sale therefore does not become the operative legal cause, even if an offer and acceptance have been pronounced.

This differs from a valid sale awaiting a further step such as payment or delivery. Here the subject itself is legally unsuitable. These are historical doctrinal examples, not modern instructions for transacting in persons.

6. Suspension of an act upon a future condition

فإن التعليق منع انعقاد التصرف علة قبل وجود الشرط
Suspension prevents the act from constituting an immediately operative legal cause before the condition occurs.

When a performative legal utterance is suspended on a future event, the legal effect does not simply arise at the time the words are spoken. The existence of a conditional undertaking and the present operation of the intended ruling are distinct.

For example, a conditional divorce pronouncement does not, in this doctrinal example, necessarily effect divorce immediately before the stipulated event occurs. Its effect must be considered when the condition is fulfilled.

7. An oath and a conditional divorce

ولهذا لو حلف لا يطلق امرأته، فعلق طلاق امرأته بدخول الدار لا يحنث
If a person swears not to divorce his wife and then makes divorce conditional on her entering a house, he does not break the oath merely by making the conditional declaration.

The reasoning is that the divorce the oath addresses has not immediately taken effect simply through the suspended wording. Making a conditional pronouncement and the present occurrence of divorce are not identical.

This is an analysis of the specific classical wording and legal setting; it should not be generalized to every oath or conditional divorce without examining the applicable conditions.

8. Second: preventing completion of the cause

مانع يمنع تمامها
An impediment that prevents a cause from reaching completion.

There may be an initial legally meaningful basis, but the required duration, constituents or evidentiary steps have not all been satisfied. A subsequent event prevents the legal ground from becoming complete.

The distinction from the first type is critical: in the first, the cause cannot be constituted at all; in the second, an initiated basis fails to reach the required completeness. Loss of qualifying zakat wealth during the year and failure of a necessary witness are the text's illustrations.

9. Loss of nisab during the zakat year

هلاك النصاب في أثناء الحول
Destruction of the qualifying nisab during the zakat year.

Possessing nisab at a moment is not identical to meeting the full conditions for a completed zakat year. In the classical case discussed, the qualifying property is lost during the year so that the legally required completion of the ground is prevented.

This is not simply late payment of a zakat debt already fully established. The impediment concerns completion of the operative cause. Lesser fluctuations and later reacquisition of qualifying property involve additional rules not settled by this example alone.

10. Incomplete testimony as an impediment

وامتناع أحد الشاهدين عن الشهادة
The refusal of one of two witnesses to give testimony.

Where a specific legal claim requires two qualifying testimonies, one witness alone does not complete the evidentiary foundation. The refusal of the second witness blocks completion of the legal ground on which the judgment would depend.

The example concerns cases requiring this form of proof. It is not a universal rule that a single person's information can never carry legal weight; the evidentiary requirements differ among legal contexts.

11. Rejection of part of a contract

ورد شطر العقد
Rejection of a portion of a contractual act.

Where a contract requires complementary components, the presence of one component is insufficient. Rejection of the other necessary component prevents the complete legal transaction from being established.

For illustration, an offer without legally effective acceptance does not complete a bilateral contract. The source says shaṭr al-ʿaqd (a part of the contract), not sharṭ al-ʿaqd (a condition of the contract); confusing these two words would change the teaching point.

12. Third: preventing a ruling from commencing

ومانع يمنع ابتداء الحكم
An impediment preventing the initial commencement of a ruling.

At this stage the legal basis is recognized, but a further legal factor blocks the intended effect from taking immediate operation. This is different from a nonconstituted or incomplete operative cause.

The central question becomes: assuming the relevant contractual or legal basis exists, what additional right or circumstance prevents the expected legal effect from beginning now? The source illustrates this with an option stipulated in a sale and the continuing prayer time of an excused person.

13. A sale with a stipulated option

ومثال الثالث: البيع بشرط الخيار
The third type is illustrated by a sale with a stipulated option.

The essentials of a sale may be present, while an option allows a party to affirm or rescind the transaction during an agreed period. The option prevents certain legal effects from taking effect with the same immediate finality as in a fully binding sale.

This differs from the attempted sale of something legally unsuitable as sale property: that fails at constitution. Here a legal act has been constituted, and the impediment concerns the inception of particular effects. Exact consequences depend on which party has the option and the applicable doctrine.

14. Continued prayer time for a legally excused person

وبقاء الوقت في حق صاحب العذر
The persistence of prayer time in the case of a legally excused worshipper.

In Hanafi jurisprudence, certain rules of purification for a person with a continuing minor-impurity condition are associated with the current prayer period. During that period, the ongoing excuse does not repeatedly invalidate the person's purification in precisely the way an ordinary nullifier would.

The remaining prayer time thus blocks the immediate operation of a particular legal consequence. The rules concerning the time's end, verification of the chronic excuse, and other nullifiers must be examined separately. This cannot be generalized to an unaffected worshipper.

15. Fourth: preventing continuation

ومانع يمنع دوامه
An impediment that prevents the continuation of a ruling.

Here a legal effect has already arisen, but a recognized right of rescission or another relevant event can interfere with its persistence. The distinction from blocking commencement concerns the legal state: has the effect not yet arisen, or does an already existing effect become subject to termination?

The source lists options relating to puberty, emancipation, inspection of goods, lack of marital suitability, and healing in the law of injuries. Each needs to be understood in its own legal context rather than treated as an automatic, universal cancellation.

16. The option arising at puberty

خيار البلوغ
The option associated with reaching puberty.

In specified historical Hanafi marriage scenarios involving a marriage contracted during minority by a guardian, an option to seek dissolution could arise upon reaching puberty. The marriage had a legal effect before the later option arose; the option concerns continuation of that pre-existing effect.

This is not a universal claim that every marriage contracted during minority gives an identical option. The guardian's status, contract and conditions matter. The doctrinal point is that a subsequently arising right can affect the persistence of a previously established ruling.

17. The option connected with emancipation

والعتق
The option connected with emancipation.

In the historical legal institution of slavery, particular circumstances surrounding the emancipation of a married enslaved woman could give rise to an option concerning the persistence of her marriage. The option arose after the original contract had operated.

It is therefore classified as affecting the continuation of the ruling, not as proof that the original contract was never constituted. This explains historical doctrine and is not a suggestion or permission to engage in modern trafficking or sales of persons.

18. The buyer’s option upon inspection

والرؤية
The option arising on inspection.

In certain classical sale transactions a buyer purchases an item not yet inspected. Upon later inspection, the buyer may gain a recognized right to affirm or rescind the sale.

The initial sale existed before inspection; the later option can affect its persistence. This explains why it appears under impediments to continuation. It should be distinguished from a stipulated option: the latter arises from an agreed contractual provision, whereas the inspection option concerns later examination of the goods.

19. Lack of marital suitability and a later objection

وعدم الكفاءة
The lack of legally relevant marital suitability.

In particular Hanafi marriage doctrines, kafāʾa concerns defined suitability considerations that can give certain eligible parties a right to object to, or seek dissolution of, an existing marriage. A contract may have been constituted even though such a subsequent challenge is possible.

The conditions, entitled parties, timing and loss of this right require separate legal analysis. The lesson's point is limited: a defect may give rise to a later challenge to an established contract rather than necessarily preventing its original constitution.

20. Healing of injuries and continuing consequences

والاندمال في باب الجراحات
Healing in the chapter on injuries.

Liability and related legal consequences for an injury may depend on whether the wound heals or later develops further consequences. Healing can restrict outcomes that depended on the continuation or progression of the injury.

The general teaching point is that later developments can change how an existing legal matter continues to operate. This passage alone does not determine a particular amount of compensation or a specific retaliation rule; those require the detailed law of injuries.

21. Classifying the worked examples by stage

CaseTypeWhy?Unsuitable sale subjectFormationNo operative contract arisesLoss of nisab during yearCompletionRequired basis is not completedSale with stipulated optionCommencementImmediate effect is restrictedOption upon inspectionContinuationAn existing sale becomes defeasible

The term impediment thus covers four legally different operations. Ask whether the obstacle concerns the legal cause or the legal ruling, and, if the ruling is involved, whether the difficulty is its inception or its persistence.

22. Why specification of the cause is disputed

وهذا على اعتبار جواز تخصيص العلة الشرعية
This classification presupposes that specification of a legal cause is admissible.

The theoretical question is whether a cause can be fully realized while its otherwise expected legal effect is blocked by a recognized impediment. One approach allows this possibility and describes a completed cause whose effect is restricted by an obstacle.

Another approach maintains that when the complete effective cause is present, the ruling must follow. On that analysis some apparent impediments must instead be located in the formation or completion of the cause. The disagreement concerns the logical relation between cause and legal effect.

23. The alternative threefold account

فالموانع عنده ثلاثة أقسام
On the alternative view, impediments have three categories.

For scholars who reject specification of a legal cause, the classification is:
1. An impediment preventing the cause from beginning.
2. An impediment preventing its completion.
3. An impediment preventing the ruling's continuation.

A separate category blocking the commencement of the ruling after full completion of its cause is not accepted on this analysis. If the effective cause truly becomes complete, the legal effect must follow; the obstacle must instead be understood in an earlier stage.

24. The consequence of a completed cause

وأما عند تمام العلة فيثبت الحكم لا محالة
Once the operative cause is complete, the ruling necessarily follows.

This is the decisive premise of the position rejecting specification of the legal cause. If an operative cause is complete in all its requirements, this view does not recognize a separate obstruction that entirely prevents the ruling from initially arising.

In analyzing matters such as a sale with an option, jurists can differ over whether the operative cause itself has fully matured. Their specific legal conclusions also depend on further doctrines. This abstract principle does not independently settle every type of contractual option.

25. Putting the four types to work

Four diagnostic questions
1. Is the legal act, including its subject matter, capable of becoming an operative cause? If not, constitution is blocked.
2. Have the elements and legally required duration been completed? If not, completion is blocked.
3. Is a recognized right or condition preventing the initial legal effect even though its basis has arisen? This is the issue of blocked commencement.
4. Did the ruling previously arise and only later become subject to termination or rescission? This concerns continuation.

Keep noncompletion of the cause separate from subsequent cessation of a ruling. Where specification of the cause is disputed, explain why jurists may use either a fourfold or threefold classification.
