The First Testimony: Radical Tanzih
La ilaha illa’llah (There is no god but God) in Ismaili ta’wil encodes a deeper claim than simple monotheism. The word ilaha (commonly translated “god”) is read as any ultimate — any thing that the human heart might take as its final ground or locus of meaning. The testimony denies all such ultimates except the divine.
But in Ismaili neoplatonist cosmology, God is radically transcendent (al-tanzih) — beyond all predication, beyond “being” even. God does not “exist” in the way things exist; God is the source of existence. So the first testimony, in ta’wil, clears the field of all ultimates while simultaneously acknowledging that the divine is beyond all available concepts.
The Second Testimony: Mediation
Muhammadun rasul allah (Muhammad is the Messenger of God) in ta’wil declares that the divine, while radically beyond all knowing, reaches human beings through a specific chain of mediation: the Prophet, then the Imam who continues his function in each generation.
The second testimony is not an addendum to the first — it is the practical consequence of the first. Because God is beyond unmediated human access, the chain of mediation (Prophet → Imam) is the only way the transcendent reality reaches the world. The second testimony is the structural answer to the existential question posed by the first.
Together
The two testimonies together declare: (1) the divine is beyond all ultimates; (2) the divine reaches us through Muhammad and his designated successors. This is the full Ismaili meaning of the shahadah — it combines radical transcendence with the necessity of mediated guidance.
