He has made significant contributions in various areas, such as serving as a key member of the Lajnatut Talaba for the expansion of Bengali Islamic literature.

He has a significant role as a cornerstone of the Bengali Islamic literature, as a member of the organization called Lajnatut Talaba, which demanded the expansion of the Bangla language.

To that end, he founded a madrasa called Jamiatul Islah Al-Madania in Ichhapur village, located in the Jaora Union of Thakurgaon.

He arranges an annual four-day Islahi Ijtema on the grounds of the madrasa, drawing scholars, educators, and the general public from far and wide.

[9] In addition to this madrasa, he established Jamia Iqra Bangladesh in Rampura, Dhaka, of which his younger brother Arif Uddin Maruf is currently the chairman.

[11] He also urged Shah Ahmad Shafi, the former chairman of the Bangladesh Qawmi Madrasa Education Commission, to be honored with the Independence Award at the same event.

In 2006, Islamic scholars gathered to demand recognition for Qawmi madrasas from former Prime Minister Khaleda Zia, but their efforts were unsuccessful.

Later, under Sheikh Hasina's government, a committee was formed to focus on implementing recognition, with Shah Ahmad Shafi as the chairman and Farid Uddin Masood as the co-chairman.

The Bangladesh Jamiyatul Ulama, one of the country's largest Islamic groups, endorsed the fatwa, and its leaders have called on the government to enforce it and take strong action against violators.

[19] The International Criminal Tribunal had accused Jamaat-e-Islami of war crimes, and in 2006, Masood began a political resistance movement against the party.

[21] He established a charitable organization named Islahul Muslimin Parishad that offers aid during natural disasters in various regions across the country.

The organization carries out several social welfare programs, including distributing food aid to those affected by floods, providing medical treatment and supplies to the sick, and generating employment opportunities for the impoverished.

[23][24] These events provide essential items such as wedding attire and equipment for orphaned and underprivileged grooms and brides, as well as vehicles, sewing machines, and goats for employment purposes.

The organization also collaborates with The Asia Foundation to conduct teacher training programs for madrasas and promote women's rights in various locations.

[25] Moreover, the Islahul Muslimin Parishad has provided relief supplies to Rohingya refugee camps and assistance to families affected by the COVID-19 pandemic throughout Bangladesh.
