Why This Headline?No, the son of Maimonides — Rabbi Abraham ben Moses ben Maimon (also known as Rabbeinu Abraham or Abraham Maimonides, 1186–1237) — did not convert to Islam. He remained a devout Jew throughout his life: leader (Nagid) of the Egyptian Jewish community, court physician to the Ayyubid sultan, biblical commentator, philosopher, halakhist, and theologian.

This bold experiment sparked fierce controversy, including accusations that he was “Islamizing” the synagogues.Brief Background

• Only son of Moses Maimonides (Rambam); born in Egypt when his father was already 51 years old.
• At age 18, after his father’s death in 1204, he inherited the position of Nagid (official head of Egyptian Jewry) and became the sultan’s personal physician.
• Major works include:
  • A Torah commentary emphasizing the plain meaning (peshat).
  • Milhamot Hashem (“Wars of the Lord”) — defense of his father’s Guide for the Perplexed.
  • His magnum opus Kitāb Kifāyat al-ʿĀbidīn (“The Sufficient Guide for the Servants of God”), written in Judeo-Arabic — a massive ethical-mystical treatise.
  • Numerous halakhic responsa and letters.

Connection to Maimonides’ 13 Principles of FaithMaimonides formulated the Thirteen Principles of Faith (in his Commentary on the Mishnah, Sanhedrin 10) as the fundamental, binding dogmas of Judaism: existence of God, His absolute unity, incorporeality, prophecy, Torah from Heaven, the Messiah, resurrection of the dead, etc. Denying any of them makes one a heretic who has left the Jewish people.Abraham Maimonides fiercely defended these principles. He regarded his father as “the Great Eagle” and continued his intellectual legacy. In Kifāyat al-ʿĀbidīn he expands especially on bitachon (complete trust and reliance on God) as the highest level of faith. He believed Egyptian Jewry was suffering from a deep spiritual crisis — excessive formalism and lack of inner depth — and therefore sought powerful tools to make the 13 Principles living realities in people’s hearts.Why Did It Look Like “Conversion to Islam”? The Sufi InfluenceAbraham Maimonides greatly admired the Sufis, calling them “the true heirs of the prophets” (including Abraham and Moses). He openly proposed adopting certain Sufi methods to deepen Jewish worship:

• Solitude and seclusion (khalwa / hitbodedut)
• Intensive inner purification of the soul
• Moral stations (maqāmāt)
• Additional prostrations and bowing during prayer
• Ritual washing before prayer
• Seeking divine illumination (ilham)

He argued that these practices were not foreign but actually ancient Jewish/prophetic ways that the Sufis had preserved and imitated.Opponents (mainly traditionalists from the “Bnei ha-Shishi” faction and those loyal to the customs of the Land of Israel) reacted with outrage:

• “You are turning our synagogues into mosques!”
• They even complained to the Muslim authorities — an extremely dangerous move in those times.

Abraham defended himself vigorously: “I force no one; these practices are voluntary for me and my close circle.” The polemic lasted for years. Eventually he signed public declarations that he was not imposing changes on the community.Why Did He Do It? Deeper Reasons

1. Spiritual Crisis Diagnosis — Rabbinic Judaism of his era felt too dry and intellectual; Sufism offered practical tools for personal, experiential closeness to God.
2. Continuation of His Father’s Path — Rambam was a rationalist but also wrote about prophecy as the ultimate human achievement. The son fused rational philosophy with living mysticism.
3. Cultural Environment — 13th-century Egypt under the Ayyubids was saturated with vibrant Sufi orders.
4. Restoring “Authentic Judaism” — He believed he was recovering lost prophetic traditions rather than importing something alien.

His movement (“Hasidei Mitzrayim” — the Pietists of Egypt) survived for about another century but never became mainstream.Summary — Why the Provocative Headline?The headline “Did he convert to Islam?” is clickbait that refers to a real historical controversy. Abraham Maimonides did not convert, but he deliberately drew close — culturally and spiritually — to Islamic (especially Sufi) models in order to strengthen and revitalize core Jewish beliefs. It was a radical theological experiment that provoked strong opposition precisely because it looked so “foreign.”He stayed completely loyal to his father’s 13 Principles, defended them passionately, and used new Sufi tools to make them vibrant and alive. This episode remains one of the most fascinating examples of creative Jewish–Muslim dialogue in the Middle Ages — mutual influence without loss of Jewish identity.

2. The Video: “Al-Ghazali and the Son of Maimonides: Jewish Theological Revolution or Islamization?”The exact video you are looking for is titled:
“Al-Ghazali and the Son of Rambam: A Jewish Theological Revolution or Islamization?” (Part 1)It belongs to the excellent Hebrew YouTube series “Palimpsest – History, Thought and Literature” hosted by Dr. Dalia Cohen-Kanoh.Video Details

• Host: Dr. Dalia Cohen-Kanoh
• Guest: Dr. Yoav Aftalion — author of the book Derech ha-Lev (“The Way of the Heart”) which compares the two thinkers.
• Main Topic: The profound influence of the great Muslim theologian and mystic Abu Hamid al-Ghazali (1058–1111) on Rabbi Abraham Maimonides.
• Core Question: Was Abraham Maimonides’ project a genuine Jewish theological revolution (revival and deepening of authentic Jewish spirituality) or was it Islamization (dangerous foreign influence that threatened Jewish identity)?

The discussion is based on Dr. Aftalion’s research, which reveals astonishing parallels — sometimes nearly verbatim — between Abraham Maimonides’ Kifāyat al-ʿĀbidīn and al-Ghazali’s masterpiece Iḥyāʾ ʿUlūm al-Dīn (“The Revival of the Religious Sciences”).Key Points Covered in the Video

• Al-Ghazali: One of the most important Sunni Muslim thinkers who successfully synthesized Islamic law (fiqh), theology (kalam), and Sufi mysticism, making mysticism respectable in orthodox circles.
• Abraham Maimonides: Viewed Sufis as preservers of the prophetic path and borrowed their practical methods (solitude, heart purification, moral stages, deep contemplative prayer) to breathe new life into Judaism.
• Remarkable similarities in concepts and even phrasing: ways to combat base desires, asceticism, complete trust in God (bitachon/tawakkul), spiritual illumination, etc.
• The contemporary controversy: accusations of turning synagogues into mosques through added prostrations and washings.
• Aftalion’s conclusion: This was mutual fertilization and creative dialogue — not assimilation. It enriched Jewish faith, especially the principles of trust in God and direct spiritual experience.

The video is a natural continuation of the first topic: Abraham did not become Muslim, but he created a “Sufi-style Judaism” under Muslim mystical influence in order to heal what he perceived as the spiritual shallowness of his generation.Where to WatchSearch on YouTube:
“Palimpsest Al-Ghazali Son of Rambam” or “Yoav Aftalion Dalia Cohen-Kanoh”.
The episode (Part 1) was uploaded in May 2026 and is available on the channel “Palimpsest – History, Thought and Literature”. A Part 2 is likely available as well.Dr. Yoav Aftalion’s Hebrew book Derech ha-Lev is highly recommended for anyone who wants to go deeper.
