[3][4][5] Qasemi was born on 5 March 1935, to Bengali Muslim parents Moulvi Muhammad Muddassir and Umme Habiba in the neighbourhood of Nayabasti, located in the island of Sandwip, off the coast of Chittagong District.

Among his teachers were Idris Kandhlawi, Jamil Ahmed Thanvi, Ziaul Haq Kembelpuri, Yaqub Hazarvi, Ghulam Mustafa Hanafi, Abdul Ghani Sunni and Rasul Khan.

He played an important role in the establishment of Jamia Islamia Darul Uloom Madania madrasa in Jatrabari Thana, serving as an unpaid teacher there for one year.

[9] After the independence of Bangladesh in 1971, he became the principal of Kashiful Uloom Madrasa in Shulukbahar, Chittagong and the imam and khatib of Dampara Baitul Aziz Mosque.

[8] Qasemi was closely associated with the Jamiat Ulema-e-Islam Bangladesh, serving as vice-president, executive president and three-time elected secretary-general within a period of over thirty years.

When Fazlur Rahman Malik was appointed head of the Central Institute of Islamic Research in Karachi by the President of Pakistan Ayub Khan in 1961, Qasemi organised a vigorous movement against it in Bengal.

The East Pakistan Jamiat Committee was founded on 16 March 1966, with Abdul Karim Shaykh-e-Kouria elected as its president and Qasemi as secretary-general.
