A small number of Muslim families from neighbouring Bengal also settled in Gour, possibly following Malik Ikhtiyaruddin Iuzbak's 1254 Azmardan Invasion. One day, Ghazi Burhanuddin - who lived with his family in Tultikar - sacrificed a cow for the aqiqah of his newborn son, Gulzar Alam. Gour Govinda, in a fury for what he saw as sacrilege due to his Hindu beliefs, had the newborn killed as well as having Burhanuddin's right hand cut off. Shortly after this incident, Qadi Nuruddin of Taraf celebrated his son's marriage ceremony by slaughtering a cow for them to eat. The Qadi was executed by the feudal ruler Achak Narayan. After both men being punished, Burhanuddin and Nuruddin's brother, Halimuddin, travelled to lower Bengal where they addressed their issue with Sultan Shamsuddin Firoz Shah. This marked the start of the Conquest of Sylhet in 1303, with the Sultan appointing his nephew, Sikandar Khan Ghazi, to lead an army against the Raja. A number of battles took place, with Govinda managing to defeat the Muslims of Bengal. However, in the final battle, Govinda fled with his family following the arrival of the warrior-saint Shah Jalal and his companions, numbering over three hundred. Sikandar Khan Ghazi was appointed the first Wazir of Sylhet, and Tungachal would subsequently be captured off Achak Narayan in the following year by Syed Nasiruddin and his 12 lascars.
