[1] Initiated by Imam ‘Ali ibn Musa al-Rida, then at-Taqi, an-Naqi, al-‘Askari, and saw al-Mahdi.  He explained through his teachings of fana and baqa the statements of Ja’far al-Sadiq, who declared, “We are the Most Beautiful Names of Allah”, and his father Muhammad al-Baqir, who declared, “We are the Wajhullah (Face of God)”.  Bayazid died the same year as Hasan al-‘Askari and was present at his funeral.  

[2] Initiated Ghawth al-Adham Shaykh ‘Abd al-Qadir al-Jilani during his youth.  Predicted Shaykh ‘Abd al-Qadir al-Jilani would be the next Ghawth and would declare in Baghdad, “My foot is on the neck of all Saints”.

[3] Transmitted knowledge from Yusuf Hamdani to Shaykh ‘Abd al-Qadir Jilani.

[4] He was a descendant of the Golden Chain of Imams from the Ahl al-Bayt of the Prophet Muhammad. His lineage is described as under: Sayyid Baha-ud-din Naqshband Bukhari, son of Sayyid Muhammad Bukhari, son of Sayyid Jalal-ud-din, son of Sayyid Burhan-ud-din, son of Sayyid Abdullah, son of Sayyid Zain al-Abidin, son of Sayyid Qasim, son of Sayyid Sha’aban, son of Sayyid Burhan-un-Din, son of Sayyid Mahmud, son of Sayyid Bulaq, son of Sayyid Taqi Sufi Khilwati, son of Sayyid Fakhr-ur-Din, son of Sayyid ‘Ali Akbar, son of Imam Hasan al-‘Askari, son of Imam ‘Ali al-Hadi, son of Imam Muhammad al-Taqi, son of Imam ‘Ali ibn Musa ar-Ridha, son of Imam Musa al-Kadhim, son of Imam Ja’far al-Sadiq, son of Imam Muhammad al-Baqir, son of Imam Zayn al-‘Abidin, son of Imam Husayn ibn ‘Ali, son of Imam ‘Ali ibn Abi-Talib.

In her book “Pain and grace: a study of two mystical writers of eighteenth-century Muslim” p.32, Annemarie Schimmel writes:

“Khwaja Mir Dard`s family, like many nobles, from Bukhara; they led their pedigree back to Baha`uddin Naqshband, after whom the Naqshbandi order is named, and who was a descendent, in the 13th generation of the 11th Shia imam al-Hasan al-Askari.”

Baba Tajuddin of Nagpur claimed, “I am the grandson of Imam Hasan Askari (r.a.)”.  His lineage is traced through the venerable Khwaja Baha al-Din Shah Naqshband Bukhari.  Baba Tajuddin’s lineage tracing through Khwaja Baha al-Din back to Imam Hasan al-Askari from the offical Baba Tajuddin website with slight discrepancies is as follows:

In addition to the centuries old Sufi traditions tracing the lineage of numerous Sufi sages by descent to Imam Hasan al-Askari, a narration in the Shiite hadith collection al-Kafi also establishes Abi Muhammad al-Hasan ibn ‘Ali had relations with concubines and maids in addition to Malika Nargis throughout his life.  According to al-Kafi, in his Usool,  in the chapter of the Birth of Abi Muhammad al-Hasan ibn ‘Ali:

“When Abi Muhammad al-Hasan ibn ‘Ali became ill…the Sultan…called certain women with knowledge to deal with pregnancy.  They examined his (Abi Muhammad al-Hasan ibn ‘Ali [as]) ladies.  A certain woman had said one of the ladies is pregnant.  She was accomodated in a certain quarter…When the pregnancy was proved invalid, they distributed his legacy between his mother and brother” [al-Kafi, by Muhammad Ya’qub Kulayni.  Translated  by Muhammad Sarwar. Chap. 124, Birth of Abi Muhammad al-Hasan ibn ‘Ali, p.705].
