Mas'ūd b. ʿAbd Allah al-Bayḍawi (Persian: مسعود ب. عبدالله بیضایی) more commonly known as Baba Rukn al-Din Shirazi or Baba Rokneddin Shirazi was a 14th-century Sufi mystic[1] [2] and follower of Ibn Arabi.[3] His name means Father Rukn al-Din, the latter which transliterates as "Pillar of the Faith."
From childhood, Masud ibn Abdullah had an interest in Sufism.[4] He eventually studied and learned spirituality and started his mystical journey at a young age. He studied the basics of Sufism under Abdul Razzaq al-Kashani. He then studied the Fusus al-Hikam of Ibn Arabi under Dawud al-Qaysari, with help from Nu'man al-Khwarizmi. In adulthood, he wrote many works on Sufism and scholarly knowledge, such as a commentary and exegesis of the Fusus al-Hikam.
