In 1303, Sultan Shamsuddin Firoz Shah of Lakhnauti was engaged in a war with the neighbouring Gour Kingdom in the Sylhet region, then under the rule of the Hindu king Gour Govinda.
This began when Shaykh Burhanuddin, a Muslim living in Sylhet, sacrificed a cow for his newborn son's aqiqah (birth celebration).
Govinda, in a fury for what he saw as sacrilege, had the newborn killed as well as having Burhanuddin's right hand cut off.

When word of this reached Sultan Firoz Shah, an army commanded by his nephew, Sikandar Khan and later his Sipah Salar (Commander-in-chief) Syed Nasiruddin, was sent against Gour.
Three successive strikes were attempted, all ending in failure due to the Bengali armies inexperience in the foreign terrain as well as Govinda's superior military strategy.

A fourth attack, now with the aid of Shah Jalal and his companions (at this point numbering 360) was undertaken.
Jalal may have been summoned by Firoz Shah for aid after the initial failed attacks against Gour Govinda.
Alternatively, he may already have been present in Sylhet, fighting against the Hindu king independently prior to being approached by the Sultan.
The combined Muslim forces ultimately claimed victory against Gour.
Govinda was forced to retreat and Sylhet was brought under Muslim control.
According to tradition, Shah Chashni Pir at this point compared the soil in Sylhet with that which was previously given to Jalal by his uncle, finding them to be identical.
In any case, following the battle, Jalal and his followers settled in Sylhet.

A Persian inscription from 1303 has since been discovered in Jalal's dargah.
It mentioned Sikandar's victory in Arsah Srihat with the aid of the saint during the reign of Firoz Shah.
This inscription can now be found in Bangladesh National Museum.
