Having impressed Madani with his religious piety and enthusiasm, Chowdhury returned with him to Uttar Pradesh, where he became enrolled at Darul Uloom Deoband, a prominent Islamic university.
Following the Partition of India in 1947, Chowdhury supported the development of the newly created Pakistan, working alongside the leadership of the Jamiat Ulema-e-Hind organisation.
Chowdhury subsequently played an active part in the Bangladesh Khilafat movement, working under the leadership of Hafezzi Huzur and presiding over many of its conferences.
