The influential — and often controversial — Andalusian Muslim scholar Ibn ʿArabī was born in Murcia, Spain on this day in 1165. A mystic, Sufi philosopher, and poet, he articulated ideas that many mainstream Muslim jurists viewed as heretical, yet he remains deeply revered among followers of the Sufi tradition.
Ibn ʿArabī is considered one of the most important pillars of Sufi thought. He was a leading proponent of the doctrine of wahdat al‑wujūd — the “Unity of Being” — which holds that all existence is a manifestation of the Divine Reality. On this basis, he viewed all religions as spiritually equivalent paths toward the same truth.
He studied Islamic jurisprudence and was influenced by his fellow Andalusian scholar Ibn Ḥazm and the Ẓāhirī (literalist) school of law.
Some researchers often describe Ibn ʿArabī as an “esoteric” thinker. He observed the outward obligations of Islam and adhered to its core beliefs, yet he believed that God had granted him an inner, luminous knowledge. He claimed to receive visions both awake and asleep, and said that his departure from al‑Andalus to the eastern Islamic world (Middle East) was prompted by one of these visions.
He traveled throughout the Middle East for nearly four decades, his reputation preceded him wherever he went. Gifts and patronage reached him from every direction.
During his stay in Mecca, he met a woman renowned for her deep learning. He was profoundly influenced by her and composed delicate poetry praising her knowledge. He later wrote a Sufi commentary on those poems — a commentary that the British orientalist R. A. Nicholson translated into English in London in 1911.
Ibn ʿArabī was an extraordinarily prolific writer, leaving behind a vast collection of treatises and books. His most important work is al‑Futūḥāt al‑Makkiyya (“The Meccan Revelations”), in which he organized the scattered sciences of Sufism into 560 chapters. He also authored Fuṣūṣ al‑Ḥikam (“The Bezels of Wisdom”) in Damascus in 627 AH (1226 CE), a work that explores what he described as the three existential realities — God, the cosmos, and the human being — and presents his view of the relationship between humanity, the universe, and the Creator.
Some of his supporters argue that opponents inserted passages into Fuṣūṣ al‑Ḥikam that amount to explicit heresy, insisting that the “Greatest Master” — one of Ibn ʿArabī’s titles — is innocent of those claims.
Ibn ʿArabī’s writings provoked strong reactions among many Muslim jurists, who accused him of promoting doctrines of zandaqa (heresy), such as ḥulūl — the idea that the Divine Essence can indwell certain human beings. This concept is associated with Christian theology, which holds that God’s spirit dwelled in Jesus, whereas Islamic doctrine affirms that God “neither begets nor is begotten, and none is comparable to Him.”
Regardless of how one evaluates Ibn ʿArabī’s scholarship, his ideas created a deep rift among Muslim scholars. His supporters hailed him as “God’s pole and saint” and “the knower of God,” while his detractors saw in him a clear embodiment of heresy, calling him “the chief of the heretics” and “the lowest of idolaters.”
Among his most prominent supporters were Majd al‑Dīn al‑Fīrūzābādī, Sirāj al‑Dīn al‑Makhzūmī, and al‑Suhrawardī al‑Baghdādī. Among his strongest critics were Ibn al‑Khayyāṭ and al‑Ḥāfiẓ al‑Dhahabī. Ibn Taymiyya — one of the fiercest opponents of Sufi metaphysics — considered some of Ibn ʿArabī’s writings to contain explicit heresy, yet he also described him as “the closest of the Sufis to Islam,” noting the presence of sincere remembrance of God in his works.
