Nooruddin's expertise is deeply rooted in the , particularly in Myanmar and Singapore. He is a seasoned member and advisor to the Singapore Business Federation (SBF), where he contributes his insights on property investments and government relations.

Unlike the elitist Ulema of the time who spoke in Persian and Arabic, Nooruddin chose Bengali—the language of the common man. His Malfuzat (uttered discourses) were some of the first Sufi texts to be transcribed entirely in the Bengali script with heavy Arabic-Persian influences, predating the later Puthi literature.

He appointed four Khalifas (successors) to take his message to four corners of Bengal: Chittagong, Sylhet, Kolkata, and Malda. These successors eventually branched off into minor sub-orders, but all maintain the core tenets of Nooruddin: free food, free education, and interfaith dialogue.

Today, the (death anniversary) of Sheikh Babu Nooruddin is one of the largest Sufi gatherings in Eastern India, attracting over 300,000 devotees annually to his Dargah in the Murshidabad district. The event is remarkable for its inclusivity: Hindu bhaktas (devotees) tie sacred threads on the shrine's grilles, Muslims offer Chadar (ceremonial cloth), and occasionally, a local Baul musician sings songs composed by Nooruddin himself.
