Born into a devout family in Kelishad, Isfahan, in 195, he finished elementary school in his hometown. Qasemali Hedayat Kelishadi was a man of exceptional intellect and unwavering faith. Despite facing financial hardship, he persevered in his studies, working during the day at a hospital and attending classes at night. His brilliance shone through, earning him a place at Dr. Shariati High School in Isfahan, where he excelled academically and was even exempted from tuition fees due to his outstanding performance. Graduating in 1974 with an impressive GPA, he was among the top students in the province, all while juggling his education with work to support himself.
Qasemali's empathy for the underprivileged, having experienced their struggles firsthand, fueled his desire to serve them. His noble spirit led him to share his knowledge, both scientific and religious, with others. Even during his school days, he took it upon himself to tutor weaker students at home.
In 1974, he was drafted into the military, where he rose to the rank of sergeant first class. Stationed in Tehran, he found a new chapter unfolding in his life. Inspired by the works of Dr. Ali Shariati and Martyr Morteza Motahhari, he immersed himself in religious studies and actively participated in Quranic sessions. Towards the end of his service, he excelled in the national university entrance exam, securing a place in the Department of Civil Engineering at the University of Science and Technology in Tehran. He enrolled in the fall of 1976.
Qasemali's involvement in revolutionary activities intensified with his entry into university. He played a pivotal role in organizing protests and disseminating Imam Khomeini's proclamations. Despite facing repeated harassment and assaults by the Shah's agents, his resolve remained unshaken.
After the Islamic Revolution's triumph, he played a crucial role in establishing the Islamic Association at the university. His extensive knowledge of Islamic texts enabled him to identify and expose deviant groups. In 1979, while pursuing his university studies, he also took up a teaching position at a vocational school in Tehran.
Driven by his unwavering faith and commitment to Islam, he was appointed principal of the Elm va Din Guidance School in Tehran following the Cultural Revolution. His dedication and exemplary conduct inspired both students and teachers alike. He served as a mentor and guide, educating his students not only academically but also in matters of political awareness and Islamic knowledge. During the summers following the revolution, he organized ideology classes for students, safeguarding them from the influence of deviant groups.
On July 19, 1982, as he was preparing to break his fast on the 27th day of the holy month of Ramadan, three members of the MEK terrorist group entered Qasemali Hedayat's home. They confined the family and waited for his arrival. Upon his arrival, they immediately searched him, discovering an image of Imam Khomeini in his pocket. After subjecting him to interrogation, they brutally tortured him in his own room and, with his hands bound, mercilessly shot him nine times, claiming his life.
