## Life and educations

Agha Hossein Khansari was born on 1607 in Khansar, Iran. Before reaching the age of puberty, Agha Hossein went to Isfahan to study Islamic sciences and studied at Khajeh Molk School of Isfahan Seminary. In Isfahan, he used the presence of many professors and for this reason he called himself "the disciple of mankind" which refers to the multiplicity of his professors.
He studied the rational sciences under the tutelage of Mir Fendereski and the traditional sciences under the tutelage of Mohammad Taghi Majlesi, Khalifeh Soltan, Mohammad Bagher Sabzevari, Heydar Khansari and ... . Agha Hossein Khansari had important permits in review and issuance of Islamic scientific content, including the permission of about 20 pages from Mohammad Taghi Majlesi. Although he was afflicted with poverty during his studies, he eventually reached the point where Shah Suleiman entrusted him with the position of viceroy and overseer on the monarchy and the care of state affairs. He was proficient in rational and traditional sciences and, according to Mirza Abdollah Afandi Isfahani, was a "supporter of the scholars."

## From the point of view of others

Ali Khamenei, the current Supreme Leader of Iran, has said about the Khansari family:
   "Undoubtedly, in the list of these often unknown stars in the sky of science and culture, the great family of Khansari, especially the prominent and unique researcher, the late Agha Hossein Khansari and his son, the wise and honorable Faqih, the late Agha Jamal Khansari. In the greatness and dignity of the late Agha Hossein Khansari, it is enough that great scholars such as Vahid Behbahani and Sheikh Ansari have mentioned him with the titles of "researcher" and "master of all in all" and the like. He and his son were sages, jurists, fundamentalists, theologians, mathematicians, Hadith narrators, and writers, and they made a great contribution to the flourishing and prosperity of the cultural and scientific field of Isfahan in the middle and late Safavid period. Although some of their jurisprudential works have been used by scholars, their collection of works has never been available to Islamic scholars in an acceptable manner."
Morteza Motahhari, has said about Agha Hossein Khansari:
   "Agha Hossein Khansari, known as Mohaghegh Khansari, was brought up in the school of Isfahan and had comprehensive knowledge in rational and traditional sciences. His famous book in Fiqh is called "Mashareq al-Shomoos", which is a description on the book of "Al-Doroos" of Shahid Awwal."
