Islamic Mysticism is known as Sufism and practitioners are called Sufis. It is a belief and practice by which Muslims seek to find the truth of divine love and knowledge .
“The first stage of Sufism appeared in pious circles as a reaction against the worldliness of the early Umayyad period (661–749). From their practice of constantly meditating on the words in the Qurʾān (the Islamic holy book) about Doomsday, the ascetics became known as “those who always weep” and those who considered this world “a hut of sorrows.” They were distinguished by their scrupulous fulfillment of the injunctions of the Qurʾān and tradition, by many acts of piety, and especially by a predilection for night prayers.” 
Sufism is based on the idea that Allah is a disinterested god with neither hope for the future as fear of hell .
Sufi means ‘pure’ and believes there are ‘7 planes of existence’. Practitioners engage existence as multi dimensional . Sufism deals specifically with direct connection to a creator god or original consciousness.
Rumi is a well known Sufi poet.
Sufism intersects with Christian Hermits (mystics), plus cultures of Europe and India . Sufis practice trance and magic, especially as it is practiced in India  .
Christianity is anchored in mystical practice also , prophecy itself is a mystical practice. Christianity is born as a reformation of Judaism, also a religion with a strong mystical backbone . Religions of the world contain mystical practices and attempts to see visions and make direct connections to a divine state through varieties of prayer, meditation, trance, dance, and drumming.
The mystical is universal and its practice is found at every intersection within this imagination of Tarot History. The Eurasian Steppe is steeped in magic as is Chinese culture during 900 b.c.e to 1400 b.c.e and certainly beyond those time frames, but definitely during this era when cultures were trading and integrating and conquering in constant succession along the Steppe.
The mystics of all these backgrounds met amid the exchanges of culture created by nomadic tribalism, empire building, and the long wars of the Crusades, of course.
Mystics generally perform divination as part of their practice or follow the words of prophetic characters like Jesus.
As for the Kipchaks, their name means ‘Hollow Tree’. According to them, inside a hollow tree, their original human ancestress gave birth to her son .
As these cultures meet and exchange much integration of practice and ritual converge in ways we may only imagine.
