Yasa In , after the conquest of Bukhara, Genghis Khan had assembled the rich Muslim residents at the festival ground and had admonished them. He called them sinners and warned them to compensate for their sins by parting with their hidden wealth. The episode was dramatic enough to be painted and for a long time afterwards people still remembered the incident. In the late sixteenth century, ‘Abdullah Khan, a distant descendant of Jochi, Genghis Khan’s eldest son, went to the same festival ground in Bukhara.
Unlike Genghis Khan, however, ‘Abdullah Khan went to perform his holiday prayers there. His chronicler, Hafiz-i Tanish, reported this performance of Muslim piety by his master and included the surprising comment: ‘this was according to the yasa of Genghis Khan’.
