Ayatullah Sheikh Muhammad Kazim Khurasani (; 1839 – 12 December 1911), commonly known as Akhund Khurasani () was a Shia jurist and political activist. He is known for using his position as a Marja as legitimizing force behind the first democratic revolution of Asia that happened in Iran (1905–1911), where he was the main clerical supporter of the revolution. He believed that the democratic form of government would be the best possible choice in the absence of Imam and regarded the democratic constitutional revolution a Jihad (holy war) in which all Muslims had to participate. Along with Mirza Husayn Tehrani and Shaikh Abdallah Mazandarani, he led people against what they called a "state tyranny", issued fatwas, and "sent telegrams to tribal chiefs, prominent national and political leaders, and heads of state in England, France, Germany, and Turkey". When Mohammad Ali Shah became king of Iran, Mohammad Kazim Khorasani sent him a 'ten-point' instruction including points on protecting Islam, promoting domestic industries and modern science, stopping colonial intervention in Iran 'while retaining diplomatic relations', and establishing 'justice and equality'. He is regarded as one of the most important Shia Mujtahids of all times, and the title Akhund (the scholar) is almost exclusively used for him. He started to deliver his lectures at Najaf seminary in 1874 CE, when his mentor Syed Mirza Muhammad Hasan Shirazi left for Samarra and appointed him as his successor. He became a source of emulation in 1895 and he taught for years in Najaf until his death in 1911 CE and trained a significant number of students from different regions of the Shi'ite world. All major Shia jurists in the twentieth century were in some way related to his circle. He was known for his credibility, independent thinking and intellectual rigor. His most famous work Kifayat al-Usul (Sufficiency of Principles ()), published in 1903 established him as the supreme authority on Shia theology, where he presented the Shi'ite jurisprudential principles in a more rigorous fashion as a unified theory of jurisprudence. It was recently published for 453rd time. This book is considered the pinnacle of advanced theology and foundation of Usul al-Fiqh in Shia seminaries of Najaf and Qom. All major Shia jurists following Akhund Khurasani have written commentaries on it, the best known is written by Ayatullah al-Khoei. Lifestyle and Education Khurasani was born in Tus, a small town near Mashhad, in 1839 CE. His
