Grand Ayatollah Mirza Muhammad Hussain Naeeni

      Ayatollah Naeeni was one of the most famous religious authorities of his time, one of the greatest critics and verifiers in the sciences of fiqh and Usul, so much so that he was known as the reviver and innovator in the science of Usul. The Allamah was born in a family known for its knowledge and distinction on 15th of June 1957 coinciding with 17th of Dhul-Qi'da of 1376 A.H. in the city of Naeen located in the province of Isfahan, Iran.

       He completed his primary studies in his home town then migrated to the city of Najaf in order to continue his higher studies in Fiqh and Usul. He was taught by Grand Ayatollah Hajj Mirza Muhammad Hassan Shirazi and distinguished himself among his students. He also used to attend the classes of Ayatollah Akhund Muhammad Kadhim Khorasani in order to show his humbleness and respect for his status.
   

The Allamah stood out among the scholars of Najaf al-Ashraf due to the abundance of his knowledge and to his acquisition of the sciences of mathematics, wisdom, philosophy, Gnosticism as well as skill in Fiqh and Usul. He cultivated the science of Usul, coining anew in a new form distantly from difficulty and complexity, winning the admiration of those who were familiar with this art.

He also wrote books many of which were published including the following:
- A dissertation in what is doubtful to wear
- Wasilat al-Najat
- Reports in the science of Usul (which was printed several times)
- A dissertation in "there is no harm…"

Ayatollah Naeeni paid special attention to cultivating himself. He never abandoned performing night prayers, nor was he ever heard uttering a bad word. He used to organize his precious time and not waste it at all. He used to spend his time in either a scientific research, or looking after the affairs of people, or in helping them with their needs. He was moderate with regards to what he ate or put on, and he was extremely cautious in dealing with the public funds. He never took advantage of the blessed "Imam's share" and other rights stated in the Shari'a for his own personal benefit. Rather, he used to meet his life's expenses from his own income.

He never abandoned performing night prayers,

nor was he ever heard uttering a bad word.

Ayatollah Naeeni entered the city of Qom after a short stay in the cities of Kermanshah and Hamadan, and he was busy teaching and performing the congregational prayer service. He returned to Najaf one year after his stay in the holy city of Qom. He passed away on 14th of August 1936, after a lifetime of service, struggle and perseverance for nurturing a united generation that carries a Qur'anic message.
