Ḥusayn b. Jamāl al-Dīn Muḥammad al-Khwānsārī (Arabic:حُسَین بن جَمال الدین مُحَمَّد الخوانساري) (b.1016/1607 – d. 1098/1687), known as al-Muḥaqqiq al-Khwānsārī and Aghā Ḥusayn al-Khawānsārī, was a jurist from the fiqh school of Isfahan. He was a Shia theosophist in Safavid period in 11/17 century who was knowledgeable in philosophy, theosophy, rational, and traditional sciences.
Aqa Husayn al-Khwansari son of Jamal al-Din, known as al-Muhaqqiq al-Khwansari was a scholar in fiqh and a great Shia theosophist in Safavid period. Before he reached the age of maturity, he went to Isfahan to acquire Islamic knowledge and began his studies in the seminary of Khwaja Malik which was the forum of great men of knowledge at that time. He benefitted from many teachers and thus, he called himself "Tilmidh al-bashar" to refer to the multitude of his teachers. Aqa Husayn perfected his rational knowledge before Mir Findiriski, and traditional sciences before Muhammad Taqi al-Majlisi and received permission for the hadith transmition from him. Other teachers listed as his teachers are al-Muhaqqiq al-Sabziwari, author of al-Dhakhira and Haydar b. Muhammad al-Khwansari, author of Zubdat al-tasanif. Although he suffered poverty during his education, he reached a level Shah Sulayman Safavi sent him his own precious cloak and in one of his travels appointed him as his vicegerent to deal with the affairs of the state. Having such a great position and all the comfort he had, Aqa Husayn was always a refuge for the miserable and the needy. He was knowledgeable in rational and traditional sciences and according to Afandi al-Isfahani, he was "the support for men of knowledge".
He was first interested in kalam and philosophy, but later turned to fiqh and usul and became famous in them as the scientific and religious leader of his time. Al-Khwansari sometimes composed poems in Arabic and Persian and compiled beautiful poem collections in both languages.
He finished his education in the seminary of Isfahan and continued his studies in Khwajia Malik, beside Shaykh Lutfullah mosque. He learned rational sciences with Mirfendereski and traditional sciences with Mulla Muhammad Taqi Majlisi Awwal, Khalifat al-Sultan, Muhaqqiq Sabziwari and others.
He taught in both rational and traditional sciences and thus became famous as "Ustad al-kull-I fi al-kull". His students and pupils who themselves were regarded as great names in fiqh and theosophy were:
- Aqa Jamal al-Din Muhammad (his son), who wrote marginal notes on Sharh Lum'a
- Aqa Radi al-Din Muhammad, his other son
- Muhammad Salih Khatun Abadi who studied before him for 20 years
- Mulla Mirza-yi Shirwani, the commentator and one who wrote marginal notes on Ma'alim al-usul

This book is unfinished and Aqa Husayn could not finish the details of the discussion regarding the information about Imams (a) and discussions of Twelver Shia fiqh scholars in every topic.
