After a period of relative calm following previous military campaigns, tensions resurfaced when Mujahid, the Sultan of Gulbarga, demanded the surrender of forts and territories in the Doab region.
Tensions reignited when Mujahid, the newly appointed Sultan of Gulbarga, demanded that Bukka cede control of specific forts and territories situated on the eastern side of the Doab, between the Krishna and Tungabhadra rivers.
In response, Bukka asserted that the true boundary lay along the Krishna river and demanded the Sultan's withdrawal from the entire Doab region.

Despite this, they managed to force their way through the defile and withdrew towards Adoni with sixty or seventy thousand captives, whose lives were spared according to the pact made by his father.
They waited until Mujahid was traveling from Adoni towards Kulbarga, and on the night of Friday, April 16, A.D. 1378, while the Sultan slept in his tent, Daud and three accomplices stormed in and fatally stabbed him after a struggle ensued.
