The Required Attributes of Prophets
Classical theology (kalam) identified five necessary attributes of prophets — violations of any would undermine the trust of the community in divine guidance:
- ‘Isma (infallibility/protection from sin): prophets do not commit major sins. Scholars debated minor lapses.
- Sidq (truthfulness): prophets cannot lie.
- Amana (trustworthiness): they do not deceive or misappropriate what is entrusted to them.
- Tabligh (complete conveyance): they must deliver the entire message without concealment.
- Fatana (superior intelligence): the capacity to receive, understand, and communicate divine revelation requires extraordinary cognitive power.
Khatm al-Nubuwwa: The Seal of Prophethood
“Muhammad is not the father of any of your men, but [he is] the Messenger of Allah and the Seal of the Prophets.” (33:40)
Khatam al-Nabiyyin means no new prophet with a new law (shari’a) will come after the Prophet Muhammad. The prophetic cycle is complete. What continues is not prophethood but the Imamate: the ongoing interpretation and application of what the final prophet brought.
This doctrine distinguishes Islam from Bahá’í and Ahmadiyya movements, which Islam’s consensus regards as departing from khatm al-nubuwwa.
The Ismaili Architecture: Natiq, Wasi, Imam
Ismaili theology structures prophetic history as cycles. Each cycle has:
- A Natiq (Speaker): the prophet who brings the exoteric law — Adam, Nuh, Ibrahim, Musa, ‘Isa, Muhammad
- A Wasi (Legatee): the one who holds the esoteric interpretation — Sheth, Sam, Ismail, Harun/Joshua, Simon Peter, Ali
- An Imam: the ongoing carrier of the esoteric within the lineage of the Wasi
The Prophet Muhammad is the final Natiq. Ali ibn Abi Talib is his Wasi. The Imams of the Prophet’s lineage continue the chain of living interpretation (ta’wil) — and in the Tayyibi/Bohra continuation, the Dai al-Mutlaq acts as the Imam’s representative during the period of satr (concealment).
