Hasanuzzaman was born in c. 1900 to a Bengali Muslim family in the village of Haripur in Nangalkot, which was then under the Laksam subdivision of the Bengal Presidency's Tipperah (Comilla) District.
[3] Remaining in the home of Sir Azizul Haque in Sirajganj, Hasanuzzaman found employment as the principal of a junior madrasa.
Due to non-payment of bank money, deadlock was created and Hasanuzzaman subsequently invited the erstwhile Co-operative Registrar, Khan Bahadur Ershad Ali, to Nangalkot.
Ali was asked on behalf of the public to ease the suffering of the indebted people and so he waived the interest of 166,000 taka.
On the new moon of Falgun before the 1935 local election, Satish Chandra Kar Zamindar of Makrabpur was attacked by miscreants on his way to Haripur along with his companion Mansoor Ahmed, Maulvi Abdul Gani and his younger brother Maulvi Ali Ahmed from Tehsil Kachari.
[2] Hasanuzzaman contested as a Krishak Praja Party candidate in the 1937 Bengal legislative elections, winning in the Tippera South constituency.
On 17 January 1941, he established the Nangalkot Arifur Rahman High School and got approval and permission to conduct examinations in the same year with the help of A. K. Fazlul Huq.
During the Bengal famine of 1943, Hasanuzzaman invited A. M. Martin, the Commissioner of Chittagong Division, to Nangalkot through the co-operative department.
He ran as a Muslim League candidate during the 1954 East Bengal Legislative Assembly election but failed to win a seat.
He was the Parliamentary Secretary (currently equivalent to the Minister of State) in the Ministry of Relief and Rehabilitation during the tenure of Ghulam Farooqui and was appointed as the Whip.
He presented an anti-government speech in Parliament against President Ayub Khan's SUNSET LAW 30th Chaitra Act and said he would not hesitate to give up his seat if necessary.
In 1963, 1964 and 1965, for three consecutive years, he strongly emphasized the equitable distribution of Sarshina's annual rights and wealth.
