Abdul Razzaq Gilani

ʿAbd al-Razzāq b. ʿAbd al-Qādir al-Jīlānī (c. Dhu al-Qi'dah 528 AH – 6 Shawwal 603 AH/9 September 1134 – 7 May 1207), also known as Abū Bakr al-Jīlī or ʿAbd al-Razzāq al-Jīlānī (often simplified as Abdul-Razzaq Gilani) for short, or reverentially as Shaykh ʿAbd al-Razzāq al-Jīlānī by Sunni Muslims, was a Persian Sunni Muslim Hanbali theologian, jurist, traditionalist and Sufi mystic based in Baghdad. He received his initial training in the traditional Islamic sciences from his father, Abdul-Qadir Gilani (d. 1166), the founder of the Qadiriyya order of Sunni mysticism, prior to setting out "on his own to attend the lectures of other prominent Hanbali scholars" in his region. He is sometimes given the Arabic honorary epithet Tāj al-Dīn (Crown of the Religion) in Sunni tradition, due to his reputation as a mystic of the Hanbali school.
