Sayyid Sadr Al-Din Dashtaki or Sayyed Sanad was an Iranian Shia philosopher and theologian. He counts as the founder of the Shiraz school of philosophy.
Sadr Al din was born in Dashtah, a region near Shiraz. His complete name was Sayyid Muhammad b. Mansur Al Husayni Al Dashtaki. He was born in Shiraz on second of 829/19 June. He counted as the first in the Dastaki family who confessed apparently to shiism sect. According to Pourjavady, it seems that he was a Zaydi. He also challenged with Jalāl-al-Dīn Davānī on the legality of Shia.[1]
Dashtaki was educated along with his cousin and learned Arabic literature and Islamic law with him. He studied rational sciences with Qawam Al Din Al-Kurbali. Kurbali had an important role in introducing Sadr Al-Din to Philosophical discussion, as did Sayyid Muslim Farsi, who was the teacher of Sadr Al-Din in logic and philosophy. Sadr Al Din was also involved in building the houses.
Sadr Al-Din built a madrasah and called it Mansuriyyah, the name of his son. This Madrasah is still active in the center of Shiraz, according to Kakaei.
Sadr Al Din led a rebellion against the Ruler of Shiraz and was killed by a group of Turkmans on order of Ruler Qasem Bey. He died on 17 Ramadan 903/9 May 1498.
