IN those days, when Mirzá Abá Bakr was intent on the conquest of Khotan, he had with him Omar Mirzá. His elder brother did not approve of his proceedings, and wished to join issue with him. Upon Mirzá Abá Bakr ascertaining this, he contrived to lay hands on him, and having blinded him, sent him to Muhammad Haidar Mirzá. After the destruction [viráni] of Káshghar, Omar Mirzá went to Samarkand, where he was treated with kindness, till, in the year 921, he returned to Káshghar. Here he died, and was buried in the mausoleum of Amir Sayyid Ali.
In short, Abá Bakr being released from the molestations of his brother, continued his march upon Khotan. On the first occasion he made peace; on the second, matters were again concluded with a treaty. The two governors mounted, and having met and conferred together, they arranged the conditions of the peace, and took a solemn oath upon the Word of God, in confirmation of the agreement. Mirzá Abá Bakr, having given the bond to his own servants, handed the Korán [the Kalám Ullah]* to one of his nobles, telling him to take it to Khán Nazar Mirzá. When Khán Nazar Mirzá stretched out his hand to take the “Kalám Ullah,” the noble seized his hand with both his own, while others attacked him from every side with swords: for the followers of Mirzá Abá Bakr, having previously agreed upon this, had been standing ready. He was taken quite by surprise. None of the retainers of Khán Nazar Mirzá being able to use their arms [to help him], they fled, while some others who had been appointed for the business, seized Kul Nazar Mirzá. The two brothers were put to death with the sword, and by this ruse their seed was eradicated from Khotan; thus did Abá Bakr conquer Khotan and gain absolute power. Having finished this affair, Abá Bakr started on an expedition against his uncle, Muhammad Haidar Mirzá.
