After returning to Hyderabad, Deccan, in 1308 Hijri, Hadhrat Shaykh Ul Islam (May Allah shower His Mercy on him) founded a research organization of international repute, “Daairatul Ma’arif” to publish Arabic books of Islamic sciences. To manage these tasks, he set up a committee and made them responsible for all affairs of the organization. Many books and manuscripts were published through this organization. Those pearls and diamonds which this organization cut, polished and presented to the world can never be forgotten by the world of scholarship. Even today, this organization enjoys international repute and has become a great mark of recognition for Hyderabad.
