Why Sufi Islam and Kabbalah Jews were friends and allies?

Both Sufi Islam , and Kabbalah are mystical sects thrived in the Islamic Golden age in Al-Andalus civilization ( Islamic Spain )

And Sufism is one the peacefully sects not only in Islam but along other religions also and Sufism have birth to greatest philosophers of love in human history like Ibn Arabi , Al-Rumi

And Jews had a huge respect for Sufism :

As Abraham Maimonides the son of the Rambam called Sufi Muslims are the inheritors of the ancient Israelites

The esoteric teachings of Jewish Kabbalists in 13th-century Spain, at the time of rabbi Abraham Abulafia, show great similarities with the rituals of Muslim mystics. They include, for example, complex songs, breath control techniques, and head movements – all practices that did not exist in the Kabbalah before the Middle Ages. Abulafia introduced the ecstatic forms of the Sufi rituals of dhikr into Judaism, in which the name of God is tirelessly repeated until reaching a state of trance.

The famous Kabbalists of the Safed school, in Galileo, also seem to have been influenced by Sufism. In the 16th century, while Isaac Luria (1534-1572) – considered the father of modern Kabbalah – was active. Safed was also a flourishing center of Muslim mysticism. The city boasted of hosting a Sufi center that the Turkish traveler Evliya Chelebi (1611-1682) mentions in his stories

The parallels are striking: the Kabbalists organized spiritual concerts during which they sang mystical verses, like the dervishes. Spiritual congregations were also established around a saint, and there, too, was practiced solitary meditation and the repetition of the name of God.

Unfortunately kabbalah was perfectly integrated in Orthodox Judaism , while Sufism is widely attacked by Salafis ( Orthodox islam ) because of the using forbidden laws to interpret Quran and transform it to squares and numbers to reach the hidden realm and they accuse them to do black Magic
