Aḥmad Ḥasan ibn Waṣī ar-Raḥmān ibn Ḥamīd ʿAlī al-Jīrawī (; 1882–1967), popularly known as Shah Ahmad Hasan (), was a Bangladeshi Islamic scholar and educationist. He was an early student of Al-Jamiatul Ahlia Darul Ulum Moinul Islam in Hathazari. Hasan established Al Jameatul Arabiatul Islamia Jiri, which was the second Qawmi Madrasah of Bangladesh. Early life and education 
Ahmad Hasan was born in 1882 to a Bengali Muslim family in the village of Jiri in western Patiya under the Chittagong District of the Bengal Presidency. He received his primary education at home from a tutor. He studied the Qur'an and the Persian and Urdu languages with a tutor named Rafiqullah. In 1315 AH (1897-98 CE), Hasan enrolled at the Mohsinia Madrasa, which was the only madrasa in Chittagong. He began systematically studying at the state-run madrasa from Jamaat-e-Dahum. In 1318 AH (1901 CE), the Madrasa Moinul Islam was established in Hathazari, which was the first qawmi madrasa in Bengal. After coming into contact with Abdul Hamid Madarshahi, Hasan was admitted to Hathazari from Jamaat-e-Nahum. Among his teachers in Hathzari were Habibullah Qurayshi and Zamiruddin Ahmad. Career 
Whilst studying as Jamaat-e-Ula at Hathazari, Ashraf Ali of Kaiyagram used to have a jagir in their house.

Later, he relocated the madrasa to his village in Jiri. Sufism
