According to a handwritten manuscript by his grandfather's elder brother Abdul Hai Choudhury, the family was descended from Gawhar Khan, a nobleman from Badakhshan. Khan was said to have given up his wealth to his younger brother, and become a da'i in Hindustan, taking with him a handwritten ancestral mus'haf by Mir Husayn (dating to 1056 AH / 1647 CE), gilded by Muhammad Yusuf Ali. The emperor granted him jagirs near the village of Kaliganj, near present-day Karimganj district.[4]
Career
In 1948, Choudhury was appointed the first Shaykhul Hadith (Professor of Hadith) at the Madinatul Uloom Bagbari madrasa.[4]
