Al-Mīrzā Abu l-Qāsim b. Muḥammad Ḥasan al-Shaftī (Arabic: المیرزا ابوالقاسِم بن مُحَمَّد حَسَن الشَفتی) (b. 1150/1737-38 d. 1231/1815-16), commonly known as al-Mīrzā al-Qummī and Muḥaqqiq Qummī, was a Shi'a Marja' in the 12th and 13th centuries. He was contemporaries with some Qajar shahs and advised them to be tolerant of people and firm in their faith. Performing Salat al-Jum'a (Friday prayer) and Salat al-Jama'a (congregational prayer) were his other activities. His most important work is his book Qawanin and hence he was titled as Sāḥib Qawānīn (owner or author of Qwanin). Validity of absolute conjecture, conjoining command and prohibition in a single personal subject and permissibility of judgment for a Muqalid according to a fatwa of his Marja' were some of his special jurisprudential opinions.
Al-Mirza al-Qummi was born in 1150/1737-38 in Darr-i Bagh village (located in Japilq district, about 12 km away form Burujird) and passed away in 1231/1815-16 in Qom. 1151 and 1153 is also reported as his birthdate and 1233 as his demise date. He was entombed in Shaykhan cemetery in Qom.
His father, who was from Shaft (a village near Fuman), had studied in Hawza-i 'Ilmiyya of Isfahan (Shi'a seminary of Isfahan) and then moved to Japliq.
Al-Mirza al-Qummi studied Arabic and Farsi grammar and literature under his father in his home village, Darr-i Bagh. Then he moved to Khwansar and became a student of Sayyid Husayn Khwansari in Fiqh and Usul. After a few years he married Khwansari's sister. Then he emigrated to Karbala, Iraq, and became a student of Muhammad Baqir Bihbahani.
After a while and by getting permission from Bihbahani, he returned to Darr-i Bagh and went to Qal'-i Bano village (a village in Japliq) and then went to Kasi Garan school in Isfahan and after that went to Shiraz which coincided with the reign of Karim Khan Zand. He stayed in Shiraz for 2 or 3 years. Then he returned to Isfahan and went to Babu village and started to teach Fiqh and Usul to some Hawza students. He lived a hard life economically. Then he moved to Qom, where he thought, authored his books, became very well-known in the country and became a Marja'.
Al-Mirza al-Qummi was known as Muhaqqiq Qummi. Validity of absolute conjecture, conjoining command and prohibition in a single personal subject and permissibility of judgment for a Muqalid according to a fatwa of his Marja' were some of his special jurisprudential opinions.
