Muhammad Sultan was Hakim (Governor) of Kashgar and Aksu during lifetime of Abdul Karim Khan. He was in expedition on Talas and Chu against Kyrgyz tribes when Abdul Karim Khan died. His brother Abu Said Sultan, who was Hakim in Khotan, tried to take advantage of his absence and to take the khanship. But sympathies of Yarkand emirs were on the side of Muhammad Sultan and he was declared a Khan after returning from expedition, 3 months later of Abdul Karim Khan's death.
