The Principle of Exemption from Obligation (Bara’ah)

Up to this point, we have expounded approximately eleven preliminary introductions that were necessary regarding the Practical Principles. From today, we shall formally enter the discussion on the principle of Exemption from obligation (Bara’ah).

Intellectual Exemption

Before entering the core discussion of Exemption from obligation (Bara’ah), it is necessary to mention a preliminary point: in standard books of the principles of jurisprudence (Usul al-Fiqh), the discussion is predominantly focused on scriptural exemption (Bara’ah Shar’iyyah), whereas intellectual exemption (Bara’ah ‘Aqliyyah) has been less frequently subjected to rigorous analysis. The arguments advanced and the topics raised are mainly concerned with scriptural exemption. Therefore, in this introduction, we shall provide a brief explanation regarding intellectual exemption, focusing first on its historical background and development, and second on its rational proof.

First Point: The Historical Background of Intellectual Exemption

Intellectual exemption, in the sense that “the ugliness of punishment without declaration” (Qubh al-Iqab bila Bayan) is a rational rule, has received serious attention primarily since the era of Wahid al-Behbahani. Prior to him, although this expression may have been used in the treatises of prominent scholars and jurists, their intended meaning was not “the ugliness of punishment without declaration.” The terminology has undergone several shifts across different eras. I will now outline these expressions—which are seemingly close to this meaning and might be mistaken for intellectual exemption—to demonstrate that they did not originally signify intellectual exemption in its contemporary sense. Indeed, even when the term “intellectual exemption” was employed in certain periods, it did not denote the ugliness of punishment without declaration.

1. The Expression “Permissibility upon Doubt in Obligation” (al-Ibahah ‘ind al-Shakk fi al-Ilzam):
This expression was utilized by Sheikh al-Saduq, who posited that if we doubt whether an act is obligatory or prohibited, we rule in favor of permissibility (Ibahah). However, it is not entirely clear whether his intended meaning by “permissibility upon doubt in obligation” was truly this intellectual exemption or something else. It is highly plausible that Sheikh al-Saduq meant scriptural permissibility (al-Ibahah al-Shar’iyyah).
Our objective is to trace whether intellectual exemption has a historical precedent. While “permissibility upon doubt in obligation” is functionally equivalent to exemption, it likely refers to scriptural permissibility or scriptural exemption. Intellectual exemption or intellectual permissibility in the sense of “the ugliness of punishment without declaration” cannot be clearly attributed to the words of Sheikh al-Saduq.

2. The Era of Sheikh al-Mufid and Sheikh al-Tusi:
Following Sheikh al-Saduq, during the eras of Sheikh al-Mufid and Sheikh al-Tusi, not only was “permissibility upon doubt” not championed, but rather “prohibition upon doubt” (al-Hazr ‘ind al-Shakk) was proposed. They raised a debate regarding the primordial state of things: “Is the default state of things prohibition or permissibility?” (al-Asl fi al-Ashya’ hal huwa al-Hazr aw al-Ibahah?). Of course, this issue is raised in areas where the intellect does not independently judge an act as good or ugly. In such cases, they argued that the primary default state of things is prohibition. Their rationale was that if we commit an act about which we have doubt, we are not secure from falling into harm (Mafsadah); it might contain a hidden harm, and by committing it, we would be entangled in that harm.
This perspective is entirely foreign to the intellectual exemption under our discussion. The content of intellectual exemption is “the ugliness of punishment without declaration,” whereas this precautionary view states the exact opposite: that by committing a doubtful act, we are not safe from falling into harm.

3. The Era of Ibn Zuhrah:
In the period following Sheikh al-Tusi—which was not very distant—the term “intellectual exemption” appears in the writings of Ibn Zuhrah. He is perhaps the first to have explicitly used the term “intellectual exemption” (al-Bara’ah al-Aqliyyah). Yet, it remains unclear whether Ibn Zuhrah meant “the ugliness of punishment without declaration.” Ibn Zuhrah states:

“Imposing an obligation in the absence of knowledge is ugly” (al-Taklif ma’a ‘adam al-‘ilm qabih).

Compare this with “the ugliness of punishment without declaration.” He argues: “Imposing an obligation in the absence of knowledge is ugly because it constitutes imposing an obligation beyond one’s capacity” (al-Taklif bi-ma la yutaq). This justification has caused confusion among later scholars in understanding his true intent.
If we consider the sentence “imposing an obligation in the absence of knowledge is ugly” on its own, it could be aligned with “the ugliness of punishment without declaration,” though even this alignment is not without difficulty. However, the fact that he categorized this under “imposing an obligation beyond one’s capacity” complicates the matter. This assertion implies that ignorance causes the negation of capability (Qudrah)—meaning that when a person does not know something, they lack the power to perform it. This premise is highly problematic, as ignorance does not negate physical capability. Consequently, some commentators have suggested that Ibn Zuhrah meant that detailed compliance (al-Imtithal al-Tafsili) is not within one’s power, whereas general compliance (al-Imtithal al-Ijmali) through precaution (Ihtiyat) remains possible. Thus, they interpreted Ibn Zuhrah’s words as referring to the inability to achieve detailed compliance.

Question: The phrasing does not seem to address punishment at all; it suggests that it is incumbent upon God to declare how, for instance, the prayer is to be performed so that people may know it, because if they do not know, they cannot perform it. But he did not say that if He does not declare it, punishment is ugly.

Professor: Why? We say that punishment without declaration is ugly because the obligation of prayer… if God has not declared the details of prayer, people cannot perform it. Yes, they cannot perform it. But our discussion is not about that. Our discussion is: when God has not declared how the prayer is, how are people supposed to pray? What does this entail? We want to see whether the “intellectual exemption” mentioned by Ibn Zuhrah is identical to “the ugliness of punishment without declaration,” and we say: no. Why? Because he says: “the ugliness of obligation in the absence of knowledge”… You are merely pointing out the very ambiguity that exists in his words. Therefore, although the term “intellectual exemption” is present in Ibn Zuhrah’s text, his intended meaning is certainly not “the ugliness of punishment without declaration.”

4. The Era of Al-Muhaqqiq al-Hilli:
After this, the issue did not receive significant attention for some time until Al-Muhaqqiq al-Hilli raised the issue of exemption and argued for it. In his terminology, intellectual exemption does not appear in this sense. However, Al-Muhaqqiq al-Hilli’s arguments for exemption are noteworthy and highly relevant to our discussion.
In one formulation, he argues based on the “continuity of the state of intellect” (Istishab Hal al-Aql). What does this mean? It means that before the legislation of the Shari’ah and before any law was communicated to him, man had no obligation. Now, we doubt whether an obligation has been established in this specific case or not. We apply the “continuity of the state of intellect,” which is the Postulate of Continuity (Istishab) of the non-existence of obligation prior to legislation, or primordial non-existence (al-‘Adam al-Azali). According to this formulation, exemption is based on the Postulate of Continuity (Istishab), making the latter the reference point for the former.
Now, if we consider the proof of exemption to be the “continuity of the state of intellect,” can we say this is identical to “the ugliness of punishment without declaration“? That is, is the “continuity of the state of intellect” the same intellectual exemption that is prevalent today? Certainly not. The ugliness of punishment without declaration is conceptually distinct from the “continuity of the state of intellect.” Thus, we can assert that in this formulation, there is no trace of intellectual exemption in its contemporary sense, which became widespread from the time of Wahid al-Behbahani onward.

The second formulation mentioned by Al-Muhaqqiq al-Hilli is that “imposing an obligation on something without establishing a proof for it is ugly”; meaning it is ugly for the Lawgiver to obligate us to something without having set up an indicative evidence for it. He then states: “The non-arrival of a proof is indicative of the non-existence of the proof.” Consequently, he concludes that an obligation is ugly if no proof exists for it.
Thus, he placed two premises together to conclude that an obligation for which no proof is found is ugly:
First premise: Imposing an obligation for which no proof has been established is ugly.
Second premise: When we search and find no proof, it becomes clear that no proof exists.
Conclusion: No obligation exists, because obligation without proof is ugly.
For now, we are not concerned with the validity or invalidity of this argument.

Question: …

Professor: “The non-arrival of a proof is indicative of the non-existence of the proof.” That is, if we search in the likely places of its existence and do not find it, this indicates its non-existence. If something were required and commonly encountered by people, yet there is no trace of it anywhere, it becomes evident that there is no proof for it.
We are not currently concerned with evaluating his formulation. The main point is to see whether this argument aligns with “the ugliness of punishment without declaration.” This, too, does not correspond to intellectual exemption. The content of intellectual exemption is “the ugliness of punishment without declaration,” whereas his argument is “the ugliness of obligation without establishing a proof.” These two are distinct.
Thus, through these four historical stages, you observe that intellectual exemption with this specific content did not exist in the vocabulary of the early jurists.

5. Categorization under Intellectual Proofs:
After Al-Muhaqqiq al-Hilli, it became common to categorize exemption among the intellectual proofs (al-Adillah al-Aqliyyah). This is because both formulations advanced by Al-Muhaqqiq to prove exemption are rational: “the continuity of the state of intellect” in one sense (even though the Postulate of Continuity (Istishab) itself is scriptural, the continuity of the state of intellect refers to the state prior to the Shari’ah), and “the ugliness of obligation without establishing a proof” is also a rational judgment. Therefore, after Al-Muhaqqiq, exemption was placed within the category of intellectual proofs.

Question: …

Professor: As I mentioned, the Postulate of Continuity (Istishab) is scriptural, but if you recall, we previously stated that the early scholars believed the Postulate of Continuity (Istishab) was established by the judgment of the intellect; we are speaking from their perspective. We do not wish to evaluate this now; we want to emphasize that intellectual exemption in its contemporary sense has no apparent precedent prior to the era of Wahid al-Behbahani, regardless of whether they used the term “intellectual exemption” or not. They used phrases that suggested they were paying attention to intellectual exemption, but when we scrutinize their words, we find that what they said has no relation to “the ugliness of punishment without declaration.”

Question: …

Professor: “The ugliness of obligation without establishing a proof” is not fully identical, though it is close.

6. The Era of Wahid al-Behbahani to Sheikh al-Ansari:
From the time of Wahid al-Behbahani, intellectual exemption became famous with this specific meaning and content: that “the ugliness of punishment without declaration” is a rational rule. They posited that from the perspective of the intellect, if someone is punished for not performing an action while no declaration was made, this is ugly. This became the dominant thought among the scholars of Usul from that era onward. Naturally, in the school of Sheikh al-Ansari, this was highlighted as a fundamental element. However, even from that time, doubts were raised regarding intellectual exemption. For instance, some argued that intellectual exemption does not run in conceptual doubts (al-Shubuhat al-Mafhumiyyah). Others argued that it does not run in doubts concerning the subject matter (al-Shubuhat al-Mawdu’iyyah), because it is not the duty of the Master (Mawla) to clarify the external instances (Masadiq). He has no obligation to specify external instances; hence, we cannot apply “the ugliness of punishment without declaration” in doubts concerning the subject matter. These doubts have been raised occasionally, and indeed, some have rejected “the ugliness of punishment without declaration” entirely.

7. The Contemporary Era:
Among the contemporary scholars, the one who rejected “the ugliness of punishment without declaration” as a primary principle and rational judgment is the late Shahid al-Sadr. He completely denied intellectual exemption. His theory of “the Right of Obedience” (Haqq al-Ta’ah) is based on the rejection of “the ugliness of punishment without declaration.” This is tied to “the Right of Obedience” and “the Right of Mastership” (Haqq al-Mawlawiyyah) which he espoused. We have discussed this theory in detail, critiqued it, and rejected it in our book Al-Hukm, which has also been published independently as a concise treatise analyzing this theory.

Topic for the Next Session

This was a brief historical overview of the evolution of intellectual exemption. However, another important point remains: what is the basis of this intellectual exemption? On what grounds do you assert that “the ugliness of punishment without declaration” is a valid rule? Do those who assert this rely on a single proof, or are their proofs diverse? We shall briefly address these questions in the next session, and then, God willing, we will enter the discussion on scriptural exemption.
