Your blessed Sheikh and Spiritual Sccessorship
Hazrat Data Ganj Bakhsh had made Bayt to Hazrat Abul Fadl Muhammad bin al-Hasan al-Khuttali, he also appointed him his spiritual successor and gave Khilafat. Hazrat Data Ganj writes in his book about his Skeikh as:
He is the teacher whom I follow in Sufism. He was versed in the science of Koranic exegesis and in traditions (riwayat). In Sufism he held the doctrine of Junayd. He was a pupil of Husri and a companion of Sirwani, and was contemporary with Abu Amr Qazwini and Abul Hasan bin Saliba. He spent 60 years in sincere retirement from the world, for the most part on Mount Lukam. He displayed many signs and proofs (of sainthood), but he did not wear the garb or adopt the external fashions of the Sufis, and he used to treat formalists with severity. I never saw any man who inspired me with greater awe than he did?. Source Kashf al-Mahjub, Page 166, translated into English by Prof. Nicholson, Published by Darul Ishaat, Pakistan
