The Question
The dispute concerns a structural problem at the heart of Shia thought: if the divinely guided Imam is in concealment, who legitimately leads the believing community, and on what authority? For the Tayyibi-Ismaili tradition, to which the Dawoodi Bohras belong, the answer is the Dai al-Mutlaq — the ‘Absolute Summoner’ who has administered the da’wa since the Imam al-Tayyib, son of the Fatimid caliph-Imam al-Amir, went into concealment in the early twelfth century CE (al-Amir was killed in 524 AH / 1130 CE). The question pressed by critics is whether such an arrangement satisfies what the Imamate is supposed to provide.
What is genuinely at stake is the relationship between two ideas: that the earth is never without a divinely appointed Imam, and that for nearly nine centuries that Imam has been unseen while a deputy exercises practical authority. Both sides agree the Imam exists and is concealed; they disagree over whether deputised leadership through a Dai is a coherent and divinely sanctioned solution or a departure from the very guidance the Imamate promises.
The Twelver Critique
The Twelver critique, set out in Ali Azhar Arastu’s booklet Examining the Ismaili Imams and the Bohras, holds that the Tayyibi position concedes the practical problem it claims to solve. On this view, the doctrine of the Imamate exists precisely to furnish believers with a manifest, identifiable, divinely designated guide; an Imamate that depends on an infant who entered concealment centuries ago — and whose authority is in practice exercised by a Dai who is not himself an Imam — is said to leave the community without the present guidance the office was meant to guarantee. The critique frames this as a substitution: the Imam’s role is, in effect, transferred to a summoner.
The same booklet raises adjacent contested points used to question the broader Ismaili lineage, including the depiction of the Fatimid caliph-Imam al-Hakim bi-Amr Allah as an erratic ruler and disputes over Fatimid genealogy. These should be read as claims advanced within a polemical argument rather than as settled findings; the ‘mad caliph’ image of al-Hakim in particular is treated by modern historians as a hostile literary portrait rather than established fact.
The Ismaili-Tayyibi Response
In its own terms, the Tayyibi-Dawoodi tradition does not regard concealment as a gap in guidance but as a divinely ordained phase, a recurrence of the doctrine of satr (concealment) familiar from earlier Ismaili history. The Imam al-Tayyib is held to be present and continuing in his progeny, and the Dai al-Mutlaq leads as his deputy by delegated authority (niyaba), not as a replacement. That authority is exercised through the hudud al-din — the ranked spiritual hierarchy descending from the Imam through the Dai to subordinate ranks — so that obedience to the Dai is understood as obedience extended from the Imam himself, consistent with the Quranic command to obey God, the Messenger, and those in authority (4:59).
The tradition further argues that this structure is not anomalous within Shia Islam but parallel to it: Twelvers likewise live during the occultation of their twelfth Imam under the guidance of jurists and maraji’, so the principle of legitimate deputised leadership during concealment is, in this reading, common ground rather than a peculiarity of the Bohras. The Dai is thus presented as the steward who preserves the da’wa, transmits esoteric knowledge (tawil), and maintains the community’s bond of allegiance (walaya) until the Imam’s return.
Scholarly Assessment
Mainstream academic historians, foremost among them Farhad Daftary, describe the Tayyibi da’wa as having elaborated a sophisticated and internally coherent doctrine of the Dai al-Mutlaq’s authority during the Imam’s concealment, drawing on Fatimid-era thought and the cosmological framework of the hudud al-din. Scholars such as Wilferd Madelung and Heinz Halm situate this development in the aftermath of the Musta’li-Nizari split and the loss of the Fatimid political center, treating the office as a historically attested institutional response rather than as either self-evidently valid or self-evidently deficient — a theological question outside the historian’s remit. Academics also note as a matter of record that the line of Dais later fractured: the Dawoodi, Sulaymani, and Alavi Bohras trace differing successions following disputes from the late sixteenth century onward. Genealogical and polemical claims invoked in the debate — including hostile portrayals of al-Hakim and contested arguments about Fatimid descent — are generally regarded by scholarship as contested rather than settled.
