Duarte Barbosa quotes
The enthusiastic soldiers, who, in the thirteenth and fourteenth centuries, spread the faith of Islam among the timid race of Bengal, made forcible conversions by the sword, and, penetrating the dense forests of the Eastern frontier, planted the crescent in the villages of Sylhet. Tradition still preserves the names of Adam Shahid, Shah Halal Mujarrad, and Karmfarma Sahib, as three of the most successful of these enthusiasts.
