Highlighting the extreme humility of Hadhrat Mufti Mahmud al-Hasan Gangohi (ra) and his caution when it came to issuing fatawa, Hadhrat Mufti Muhammad Farooq Sahib Merrati  writes:

Hadhrat Mufti Mahmud al-Hasan Ganoghi (ra) never persisted on his own views. He would write fatawa and show to them to others to check and examine. He would not even consider it against his dignity to show his students his fatawa for scrutiny.

If the fatwa was an important one, he would give it to various ‘Ulama and Muftis saying, ”if there is any mistake, then let me know.”

If anyone had a suggestion, he would gladly listen to it, and if anyone made a valid and accurate objection against part of or an entire fatwa, Hadhrat would immediately accept it and most happily correct his fatwa.
