It is no exaggeration to say that the book "Al-Fusus" is the most powerful of all Ibn Arabi's works, the most profound in arrogance, and the most influential in shaping the Sufi doctrine in his time and in the generations that followed him. He established the doctrine of pantheism in its final form and established for it a complete Sufi terminology that he derived from every source he could, such as the Qur'an, Hadith, theology, Peripatetic philosophy, Neoplatonic philosophy, Christian Gnosticism, Stoicism, and the philosophy of Philo the Jew. He also made use of the terminology of esoteric Ismailism, the Qarmatians, the Ikhwan al-Safa, and the advanced Sufis of Islam. attic. But he dyed all of these terms in his own form and gave each of them a new meaning consistent with the spirit of his general doctrine of pantheism. Thus, he left behind a verbal wealth in the philosophy of Sufism, which was represented by many pantheist Sufis in the Islamic world for several centuries.
