Salman the Persian or Salman al-Farisi (Arabic: سلمان الفارسي‎ ‎ Salmān al-Fārisī), born Rouzbeh (Persian: روزبه‎ ‎ ), was a companion of the Islamic prophet Muhammad and the first Persian who converted to Islam.

 He is credited with the suggestion of digging a trench around Medina when it was attacked by Mecca in the Battle of the Trench.
 He was raised as a Zoroastrian, then attracted to Christianity, and then converted to Islam after meeting Muhammad in the city of Yathrib, which later became Medina.
 According to some traditions, he was appointed as the governor of Al-Mada'in in Iraq.
 According to popular Shia tradition, Muhammad considered Salman as part of his household ("Ahl al-Bayt").
 He was a renowned follower of Ali ibn Abi Talib after the death of Muhammad.

Muhadhdhib al-Dīn Abūʼl-Hasan ʻAlī ibn Ahmad Ibn Hubal (Arabic: مهذب الدين أبي الحس علي بن أحمد ابن هبل‎ ‎ ) known as Ibn Hubal (Arabic: ابن هبل‎ ‎ ) (c. 1122 - 1213) was an Arab physician and scientist born in Baghdad.
 He was known primarily for his medical compendium titled Kitab al-Mukhtarat fi al-tibb (Arabic: كتاب المختارات في الطب‎ ‎ ), "The Book of Selections in Medicine."
 It was written in 1165 in Mosul, north of Baghdad, where Ibn Hubal spent most of his life.
 The popular medical encyclopedia is highly dependent upon the Qanun of Ibn Sina (Avicenna), with occasional passages transcribed verbatim.

 He played a pivotal role in the study of knowledge—or epistemology, which in his context referred specifically to the theoretical elaboration of mystical/intellectual insight.
 He combined a highly original mystic-thinker, Muḥyī al-Dīn Ibn 'Arabī (1165-1240 CE/560-638 AH), whose arcane teachings Qūnavī codified and helped incorporate into the burgeoning pre-Ottoman intellectual tradition, on the one hand, with the logical/philosophical innovations of Ibn Sīnā (Lat., Avicenna), on the other.

 He made two major contributions to science, one on optics, the other on number theory.
 Farisi was a pupil of the great astronomer and mathematician Qutb al-Din al-Shirazi, who in turn was a pupil of Nasir al-Din Tusi.
