Bayazid Bastami
[5][8] Known to future Sufis as Sultān-ul-Ārifīn ("King of the Gnostics"), Bisṭāmī is considered to be one of the expositors of the state of fanā, the notion of dying in mystical union with Allah.[14] The early biographers describe him as a mystic who dismissed excessive asceticism;[15] but who was also scrupulous about ritual purity, to the point of washing his tongue before chanting God's names.[17] A measure that shows how influential his image remains in posterity is the fact that he is named in the lineage (silsila) of one of the largest Sufi brotherhoods today, the Naqshbandi order.Like his father and uncles, Bayazid led a life of asceticism and renounced all worldly pleasures in order to be one with Allah The Exalted.[21] Al-Misri had formulated the doctrine of ma'rifa (gnosis), presenting a system which helped the murid and the sheikh (guide) to communicate.Bayazid Bastami took this a step further and emphasized the importance of religious ecstasy in Islam, referred to in his words as drunkenness (Sukr or wajd), a means of self-annihilation in the Divine Presence of the Creator.Before him, the Sufi path was mainly based on piety and obedience and he played a major role in placing the concept of divine love at the core of Sufism.
