MUHAMMAD KHÁN, also, had several sons, two of whom were Shir Muhammad Khán and Shir Ali Oghlán. Shir Muhammad Khán succeeded his father, and as long as he governed, the people were peaceful and prosperous. During his reign, his brother Shir Ali Oghlán died at the age of eighteen, and thus never attained to the rank of Khán. He, however, left one son, Vais Khán by name, between whom and Shir Muhammad Khán there arose great disputes, as will be related below. Shir Muhammad Khán, who was also a contemporary of Mirzá Sháh Rukh, enjoyed a longer reign than Muhammad Khán.
