Sheikh Adi was born in the 1070s in the village of Bait Far, near
Baalbek, in the
Beqaa Valley of present-day
Lebanon. He hailed from the Umayyad lineage and was a descent from
Marwan II, who was born to a
Kurdish mother. He adhered to the
Shafi'i school. In Baghdad, Sheikh Adi was a disciple of
Ahmad Ghazali,
Abu al-Najib Suhrawardi, and
Abdul Qadir Gilani, who all studied together. Sheikh Adi then became a disciple to Hammad ad-Dabbas and then Oqeil al-Manbiji, from whom he received the
Khirqa. Sheikh Adi later qualified as an Islamic teacher and began teaching. His teachings gradually merged with local traditions. Despite his desire for seclusion, he impressed the local population with his
asceticism and
miracles. He became well known in
Kurdistan and many disciples moved to the valley of Lalish to live close to Sheikh Adi. Following this, he founded the
Adawiyya order. He used the
kunyas Al-Shami (of the Levant) and Al-Hakkari (of
Hakkari). Before he died, he named his successor his nephew
Sakhr Abu l-Barakat. In his writings he reasoned that it was God who created the devil and evil for which he cited passages of the
Quran and the
Hadiths. He also taught that the true Muslim should adhere to the teachings in the Quran and the
Sunna and that only the ones who follow the principles of the Muslim caliphs
Abu Bakr,
Uthman and
Ali are true believers. According to some sources, he established the
Sufi Adawiyya order. He is said to have performed several miraculous acts such as reading the thoughts of others, becoming invisible, and moving a mountain by force of his word. He also returned the life of a man who was crushed by a rock. == Aftermath and legacy ==
