Bismillahir Rahman Rahim,
Its prophetic name is Ihsan
Its traditional name is Tasawwuf
Its english name is Sufism
I hope to share some of the wisdoms from the scholars of Sufism.
Shaykh Akbar Ibn Arabi said, "The path to reach the knowledge of the folk (the Sufis) is through faith and piety: 'And whoever fears Allah, He shall make a way out for him, and provide him from whence he least expect' (Talaq: 3) Provision here is two types: spiritual provision, and phyiscal provision. The Exalted say, 'Fear Allah and Allah shall teach you' (2:282) This means: He shall teach you the Divine sciences what you did not know previously through intermediate means."
This illustrates the importance of having taqwa. It leads both to spiritual provision and physical provision. Have Taqwa and Allah will teach you. That is in the Quran. Taqwa is the basis for one's spiritual travel.
