Mufti Mahmood Hasan Gangohi (rah) was the senior most khalifa of Hadrat Shaykh ul Hadith Maulana Zakariyyah Kandhalwi (rah). In addition he was the Head Mufti at Dar ul Uloom Deoband and Mazaahir ul Uloom for many years. Along with the responsibilites of Ifta (Fatwa writing) he taught the 2nd Volume of Sahih Bukhari at Dar ul Uloom Deoband, supervised the running of numerous madaris in India and also compiled Fataawa Mahmoodiyah, a copious reference book on Hanafi Fiqh rulings. A man of extreme piety and learning, he was not only a Faqih and a Sufi but also a Zaahid (ascetic). Every month not only would he return his salary to Dar ul Uloom Deoband, but also add something from his own pocket also.

This great son of Islam was born in 1325 and lived to become one of the greatest luminaries of his time. Nevertheless, describing the personality of Hazrath Mufti Saheb (rahmatullah alaihi) is an almost impossible task. The most eloquent words would hopelessly fail in truly describing the knowledge, brilliance, piety, kindness, compassion, humility and the numerous other qualities which he embodied. He was an ustaad to thousands of students, a mentor to thousands of diciples and a kind and compassionate father to all who came into contact with him.
