Bonnaud encountered the works of Guénon as a young man, and became Muslim in 1979. He studied with the great Malian ethnographer and Tijani Amadou Hampâté Bâ. In 1991, he published Le soufisme : « al-taṣawwuf » et la spiritualité islamique (Sufism: "al-taṣawwuf" and Islamic spirituality) with a preface by the French Traditionalist scholar of Ibn Arabi Michel Chodkiewicz.
While working on a PhD at the École pratique des hautes études in Paris with Henri Corbin, he studied with Sayyed Jalal-ed-Din Ashtiani, an Iranian philosopher who had himself studied under the Ayatollah Khomeini (and who also taught William Chittick). Bonnaud became Shi'i himself. His PhD dissertation was later published as L'Imam Khomeyni, un gnostique méconnu du xxe siècle : métaphysique et théologie dans les œuvres philosophiques et spirituelles de l'Imam Khomeyni (Imam Khomeini, an unrecognised gnostic of the twentieth century: metaphysics and theology in the philosophical and spiritual works of Imam Khomeini).
Bonnaud moved to Iran, where he lived in the city of Mashhad, working on a very scholarly translation of the Quran into French, referring to all the leading classical Shi'i authorities, and using copious notes to summarise his researches and thus the meanings that he had decided to translate. The note explaining the bismillah at the start of the fatiha was nine pages long. He also traveled abroad as an exponent of Shi'ism, and it was on such a mission that he lost his life.
