after the death of mian noor mohammad, mian ghulam shah kalhoro's claim to rule was challenged by his brothers muradyab khan and attar khan. the latter was able to obtain sanad (authority to rule) from ahmed shah durrani and so mian ghulam shah kalhoro vacated the seat in his favour. mian attar khan could not manage the state of affairs. taking advantage of political uncertainty, khosa tribe invaded and looted local population and burnt the khudabad city down by tying fire crackers with the feet of birds and let fly them throughout the city after setting fire the fire crackers.
