Grand Ayatollah Sheikh Mohammad-Hossein Naini Gharavi (Persian: محمد حسین نائینی غروی; [mɒhæmæd-hɒsejn næene ɣæræve] May 25, 1860 – August 14, 1936) was an Iranian Shia marja'.

50th death anniversary of Ayatollah Mirza Mohammed Hussein Naini was memorialized by issue of Stamps Tickets, in Iran, in 1987.

Akhund Khurasani asked Iranian scholars to deliver sermons on the subject to clarify doubts seeded by Nuri and his comrades.

[6] His close associate and student, who later rose to the rank of Marja, Muhammad Hussain Naini, wrote a book, “Tanbih al-Ummah wa Tanzih al-Milla”(Persian: تنبیه‌ الامه و تنزیه‌ المله), to counter the propaganda of Nuri group.

Hence, the constitutional democracy was the best option to help improve the condition of the society as compared to absolutism, and run the worldly affairs with consultation and better planning.

Intellectual development in term of social progress of science can be observed between Mirza Naini and his reverenced Master Ayatollah Kazem Khorasani, which establishes the fact that difference of opinion is not the cause of hostilities the very basis of battle is ignorance.

Therefore, efforts should be made to arrange the ruling of just and honest men with duty to control the government, directly responsible to the will of God through Imam Mahdi.

[16][17] Mirza Naini being an expert on Usul al Fiqh was the first human being in the history of Iran to construe the idea of religious dictatorship.

He had written a book Tanbih al-Ummah wa Tanzih Al-Milla (the awakening of the community and refinement of the nations) which was translated into Arabic by Salih Kashi al Gheta and published in 1909 by the Institute of Strategic Studies in Baghdad.

The secondary laws, in contrast, were subject to change, depending on temporal and spatial circumstances, making them the proper sphere for legislation.
