Abstract: The past year has seen the periodic arrest by the Islamic State of a number of its scholarly figures, including Abu Ya‘qub al-Maqdisi, a man described by some as the group’s “mufti.” The crackdown on these scholars has to do with an ideological rift in the Islamic State over the doctrine of takfir. Last year, an audio series called the “Silsila ‘ilmiyya” was released with the aim of putting this dispute to rest, but the infighting has persisted and, in fact, escalated, undermining the ideological integrity of a group that claims to speak with one voice.
Just over a year ago, in mid-September 2017, the Islamic State issued a statement retracting its highly controversial memo on the issue of takfir (excommunication) and announcing its “return to the truth.” The seven-page memo, from May 2017, had been the subject of numerous refutations by the self-styled scholars (ulama) of the Islamic State, foremost among them being Turki al-Bin‘ali, the head of the Office of Research and Studies (Maktab al-Buhuth wa’l-Dirasat), who was killed in an airstrike in May 2017 while being detained by senior leaders of the caliphate.1
The statement bearing the retraction, signed by the Islamic State’s Delegated Committee (al-Lajna al-Mufawwada), foretold of an audio series that would treat the theological issues under dispute. Titled “Silsila ‘ilmiyya fi bayan masa’il manhajiyya” (“Knowledge Series Clarifying Matters of Methodology”), it appeared in six installments in the second half of September 2017.2
The purpose of the “Silsila ‘ilmiyya,” as the first episode explained, was “to unify the [Islamic] State and unite the hearts of its soldiers around the truth.” Thus far, however, it has done nothing of the sort. Far from bringing harmony, it has rather stoked further discord in the ranks of the Islamic State and its online support network. Meanwhile, al-Bin‘ali’s successor as head of the Office of Research and Studies, described by his supporters as the Islamic State’s “mufti,” is currently being detained. The charges against him may well lead to his execution, doing further damage to the group’s ideological coherence. While the Islamic State remains stronger today than is commonly thought, the internal schism over ideology is doing lasting damage in a way that has yet to be appreciated.
“The Third Nullifier”
The main reason the May 2017 memo on takfir was so controversial was that it elevated takfir to the status of a foundational religious principle. This came in the assertion that “takfir of polytheists (takfir al-mushrikin) is one of the manifest principles of the religion (min usul al-din al-zahira)”—in other words, that takfir is a duty incumbent on every true believer, and that there is no excuse for failing to fulfill it. In jihadi discourse, the notion of takfir as a requirement derives from what is commonly known as “the third nullifier” (al-naqid al-thalith), a statement by Muhammad ibn ‘Abd al-Wahhab, the founder of Wahhabism, in his list of 10 things that nullify one’s Islam (i.e., expel one from the faith). The third nullifier in the list reads: “Whoever does not excommunicate the polytheists, or is doubtful about their unbelief, or affirms the validity of their doctrine—he is an unbeliever by consensus.”3 This is to say, those who fail to excommunicate supposed polytheists, or hesitate to do so, are themselves to be excommunicated. Referring to this line, the memo attacked the “postponers” (murji’a) within the Islamic State who have sought to dilute “the third nullifier” by imposing such restrictions on it as to render it null and void. One implication of the memo was thus that those who object to this hard line have put themselves beyond the pale.a
In the eyes of the Islamic State, the “polytheists” in question are the professed Muslims living in Iraq, Syria, and other Islamic countries who have allegedly committed some act of “polytheism” (shirk). This can mean voting in a democratic system or supporting rulers who fail to rule by Islamic law, among other things. When it comes to the polytheistic nature of such practices, the Islamic State is largely agreed. Where it has had difficulty formulating a consensus is in determining which people exactly are to be deemed polytheists, and so subject to takfir, and which people, if any, may be excused their theological shortcomings on account of either ignorance (jahl) or possession of an alternative religious interpretation (ta’wil).
The view of the Islamic State’s scholars in the Office of Research and Studies has been that the third nullifier ought to be read restrictively, lest it lead to too expansive an approach to takfir. Al-Bin‘ali, for instance, in a February 2016 letter to the Delegated Committee, complained about blanket statements demanding takfir of the supporters of “idolatrous” Arab rulers, noting that some of those concerned might be exempted for one reason or another. Such statements, he warned, inevitably lead to “takfir of entire societies and peoples.”4 Similarly, in his refutation of the May 2017 memo, al-Bin‘ali argued that classifying takfir as “one of the manifest principles of the religion” opens the door to mass takfir—or, more precisely, takfir in infinite regress (al-takfir bi’l-tasalsul).5
Several years earlier, he spelled out his thinking on the subject at greater length in a lecture delivered in Raqqa.6 “Many of the nullifiers of Islam,” he declared, “are subject to rules and restrictions,” upon which he proceeded to elaborate. One of the upshots of these rules and restrictions, he said, is that most of the world’s professed Muslims are to be presumed Muslim unless proven otherwise. In particular, the inhabitants of the so-called “lapsed abode of unbelief” (dar al-kufr al-tari’)—that is, the abode of Islam (dar al-Islam) that has reverted to being the abode of unbelief (dar al-kufr) on account of the fact that Islamic law is no longer applied there—are to be given the benefit of the doubt as concerns their Islamic faith: the presumption is that they are Muslims, not unbelievers. This was a controversial position in the Islamic State, as evidenced by the outbursts of dissenting audience members at al-Bin‘ali’s lecture.b But it was representative of the more nuanced approach to takfir promoted by the Office of Research and Studies.
Those with the least nuanced approach, and hence the most prone to takfir, have been concentrated in the Central Media Department (Diwan al-I‘lam al-Markazi). The Islamic State’s Delegated Committee, its executive body, has tended to occupy something of a medial position, leaning in one direction or the other at different points in time. The May 2017 memo on takfir counted as a victory for the more takfir-prone faction identified with the Media Department, while the “Silsila ‘ilmiyya” was seen as a triumph for the more takfir-averse identified with the Office of Research and Studies. The pendulum, however, appears to be swinging back in the other direction.
Abu Ya‘qub al-Maqdisi and the “Silsila ‘Ilmiyya”
Following his death in late May 2017, al-Bin‘ali was succeeded in his role at the Office of Research and Studies by a Jordanian known as Abu Ya‘qub al-Maqdisic (not to be confused with the prominent Jordanian jihadi ideologue Abu Muhammad al-Maqdisi). While Abu Ya‘qub al-Maqdisi’s identity is as yet unknown, a brief biography online, written by a supporter, states that he has served in several positions in the Islamic State, including as a judge in two “provinces” in Syria, and is the author of 17 books and essays for the Office of Research and Studies.7 One of these books is a lengthy treatment of the “the third nullifier,” which he interprets restrictively.8 Significantly, many of the arguments and proof texts found in this book, as well as in another work of his,9 reappear in the “Silsila ‘ilmiyya” audio series, a fact that lends credence to the widely circulated claim that Abu Ya‘qub was one of the authors of the audio series.10 Another one of the authors appears to have been a certain Abu Muhammad al-Masri, who read the series in the original recording.11
The six episodes of the “Silsila ‘ilmiyya” can be summarized as follows. The first is an introduction explaining the purpose of the series, railing against “the theoreticians of extremism in takfir” and examining the causes of the current division in the Islamic State. The second treats the meaning of the term “foundation of the religion” (asl al-din), defined as consisting of four elements: “the affirmation of God, the worship of Him alone, the eschewal of the worship of all others besides Him, and dissociation from those who assign partners to God.” These are held up as necessary conditions of faith, meaning that they must be acknowledged and practiced for one to be considered a Muslim. Ignorance, it is stated, is no excuse for failing to observe these articles of faith. In other words, the principle of “excusing on the basis of ignorance” (al-‘udhr bi’l-jahl) is not operative as concerns the foundation of the religion.
The third episode is the heart of the series. Here it is argued that takfir does not form a part of the foundation of the religion, but rather is “one of the requirements of the religion” (min wajibat al-din). This is to say that while takfir of polytheists is a religious duty, it is not a foundational one. Failure to engage in takfir does not jeopardize one’s status as a Muslim. The fourth episode, building on the third, introduces the notion of “levels” (maratib) in takfir, the idea being that takfir is not always a clear-cut judgment.
The fifth episode addresses the matter of “the recalcitrant group” (al-ta’ifa al-mumtani‘a), meaning a group of people refusing to adhere to one or more of the legal obligations of the faith. While a recalcitrant group must always be fought, it is said, such people are not automatically subject to takfir. (The matter is then dismissed as irrelevant to present circumstances.) The sixth and final episode deals with the classification of lands (as the abode of Islam or the abode of unbelief) and the status of their respective inhabitants. Residence in the abode of unbelief, it is affirmed, does not necessarily denote infidel status. But the question whether professed Muslims in the “lapsed abode of unbelief” are to be considered Muslim or not is skirted.>
On its face, then, the “Silsila ‘ilmiyya” was in nearly every respect a victory for the Islamic State’s scholars against the “extremists” behind the May 2017 memo and their allies in the Media Department. Most important, they succeeded in downgrading takfir from “one of the manifest principles of the religion” to “one of the requirements of the religion,” thereby creating room for reasonable disagreement as to who is a “polytheist” and who is not.
From the beginning, however, this was a problematic victory. Not all of the episodes in the series had, in fact, been released. Moreover, both apparent authors of the series—Abu Ya‘qub al-Maqdisi and Abu Muhammad al-Masri—have been arrested several times by the Islamic State’s leadership in the course of the past year.12
The Missing Episodes and the al-Turath al-‘Ilmi Foundation
In early July 2018, an online media group called the al-Turath al-‘Ilmi Foundation (Mu’assasat al-Turath al-‘Ilmi) published the transcripts and audio files of three episodes of the “Silsila ‘ilmiyya” that had never aired.13 In an accompanying statement, al-Turath explained that the original series consisted of nine episodes, all of which had been approved by Abu Bakr al-Baghdadi.14 At the last minute, however, as the statement relates, a man named al-Hajj ‘Abdallah, who appears to be a high-ranking member of the Delegated Committee—one source describes him as the caliph’s “deputy” (na’ib)15—intervened to delay the release of three of them, on the grounds that they might upset certain “extremists” in the group.
The three missing episodes were, according to the statement, supposed to be the fourth, sixth, and seventh in the series. Of the original nine, they are the most discouraging of takfir. The fourth is a rebuttal of some of the “extremists’” arguments in favor of including takfir within the scope of the foundation of the religion. The sixth dives deeper into “the third nullifier,” explaining that it has a perilous flip side—namely, that one who wrongfully excommunicates a Muslim exposes oneself to takfir. And the seventh presents further evidence against wrongfully excommunicating Muslims. It would appear, then, that these episodes were indeed withheld as part of an effort not to alienate the more takfir-prone among the caliphate’s backers.
The statement by al-Turath goes on to say that the missing episodes were originally slated to be al-Turath’s first release upon its launch in October 2017, when it began leaking the unpublished works of the Office of Research and Studies. But it decided to give the Media Department more time. Finally, al-Turath determined that the Media Department had been recaptured by the “extremists” and purged of their opponents, at the direction of the aforementioned al-Hajj ‘Abdallah. Similarly, back in December 2017, al-Turath reported that the “extremists” had been restored to their positions in the Islamic State’s Delegated Committee, after having been sacked by al-Baghdadi in the months before.16 Indeed, the impression given by al-Turath’s various news reports is that the “extremists” are very much back in control.
From the perspective of the Media Department, the Office of Research and Studies, in cooperation with al-Turath, has gone rogue. Since October 2017, al-Turath has released dozens of books and essays by the scholars of the Office of Research and Studies, including a six-volume compendium prepared by al-Bin‘ali, in addition to numerous audio files of lectures and speeches. The Media Department has been highly critical of these unauthorized releases. In an official statement in July 2018, it instructed supporters of the caliphate not to publish or circulate such unauthorized materials—whether written, audio, or visual—claiming that “they do not represent the Islamic State, its provinces, or its leadership.”17 In his August 22, 2018, speech, al-Baghdadi said something similar, warning his supporters not to believe news reports that do not issue from the Central Media Department.18 The fact that he only referred to news reports (akhbar) is likely an indication that he does not wish to alienate the scholars of his group, however upset he may be with them.
The Charge Sheet
On August 30, 2018, a report from al-Turath announced that “the governor of al-Sham,” a man known as ‘Abd al-Qadir or Hajji Hamid, circulated a statement charging Abu Ya‘qub with several treasonous crimes. The statement was read aloud in various parts of the Islamic State.19 As al-Turath reported previously, Abu Ya‘qub had been detained on July 11, 2018, for issuing a fatwa against working in any part of the caliphate besides the military.20 The August 30, 2018, statement refers to this fatwa as a gift “on a silver platter” to the Rand Corporation, the latter seen as leading an effort to combat Islamic State media online.21
The charge sheet against Abu Ya‘qub includes the following transgressions: publishing his writings online without the consent of al-Baghdadi; defying orders to report to the frontlines; spying on the Islamic State on behalf of Abu Muhammad al-Maqdisi, the influential jihadi ideologue in Jordan who has been a major opponent of the group; dividing the ranks of the Islamic State by claiming that its rulers have acted unjustly; concealing the whereabouts of Abu Muhammad al-Hashimi, a dissident scholar who wrote a searing critique of the Islamic State in the wake of the May 2017 memo;22 rallying the group’s scholars to put pressure on the leadership to submit to their demands; collaborating with another Islamic State dissident, Abu Suhayb al-Najdi; refusing to hand over the “red stamp” bearing the logo of the Office of Research and Studies; and issuing fatwas that run contrary to the correct Sunni methodology (manhaj) on unspecified issues.
The response from Abu Ya‘qub’s camp was swift. On September 1, 2018, al-Turath released a letter of protest by a group of scholars in the Islamic State.23 In addition to defending their leader against the charges leveled against him, the authors called on the Islamic State’s rulers to hold a public trial before judges and scholars to hear the testimony of both sides. A few days later, another letter defending Abu Ya‘qub and calling for a public hearing appeared online.24 The anonymous author, who refers to himself as a student of the accused, reveals that Abu Ya‘qub is elderly and suffering from multiple medical issues—a heart murmur, sciatica pain, and degenerative disc disease. He described the charge sheet, which was read aloud in the mosques of al-Hasakah (Wilayat al-Baraka) by the chief sharia official there, as a move “paving the way to kill the shaykh.” In both letters, Abu Ya‘qub is repeatedly described as “the mufti of the [Islamic] State.”
God Save the Mufti
On September 12, 2018, the al-Wafa’ Media Foundation, an ally of the al-Turath al-‘Ilmi Foundation, appealed for divine intervention in the case of Abu Yaq‘ub. “We ask God to save the mufti of the Islamic State,” it wrote on its Telegram channel.25 Whether this prayer is answered or not, it is abundantly clear that the Islamic State’s ideological integrity, much like its territorial integrity, has been severely compromised. Al-Baghdadi has sought to hold both sides of the ideological dispute in check by striking a balance. But the balance has long been precarious, and is proving increasingly untenable. Over the past year, the scholars of the Office of Research and Studies have found themselves on the losing side of this balancing act. With the “Silsila ‘ilmiyya,” it seemed as if the balance had been restored in their favor, but they are evidently convinced that the “extremists” remain firmly in control. Meanwhile, those who hold the levers of power in the Islamic State have grown weary of the scholars’ frequent protests and leaks.
The mufti’s fate may well determine whether the Islamic State’s scholars remain in the fold, or whether they abandon the caliphate entirely. Even their continued arrest, however, could carry implications. As one disenchanted supporter recently wrote online, the Islamic State is now persecuting its scholars in the same fashion as Saudi Arabia. How will it urge people to jihad, he said, when it is engaged in such hypocrisy?26 CTC

[a] The advocates of the more hardline approach to takfir in the Islamic State have been referred to by their enemies as “extremists” (ghulat) and “Hazimis” (Hazimiyya), the latter in reference to a Saudi cleric named Ahmad ibn ‘Umar al-Hazimi. Al-Hazimi introduced a controversial doctrine known as takfir al-‘adhir, meaning “excommunication of the excuser.” Derived from a strict reading of “the third nullifier,” it stipulates that anyone who “excuses” the unbelief of an unbeliever has committed unbelief oneself and is therefore subject to takfir. Because there are disagreements among jihadis over who is and is not an unbeliever, the doctrine is highly contentious. A group of “Hazimis,” led by the Tunisian Abu Ja‘far al-Hattab, was executed in 2014, but according to al-Bin‘ali, their hardline approach resurfaced under a new guise—the demand that takfir be considered “a part of the foundation of the religion” (min asl al-din).
