Abul-Kasim tried to bribe Barkiyaruq to avoid being dismissed, loading 14 mules with as much gold as they could carry. He reached Barkiyaruq at Isfahan, but the sultan would not see him. However he told him, via intermediaries, that he had given jurisdiction to Bozan, to whom any payments should be made, and whose statements automatically became Barkiyaruq's will.

They made a noose and strangled him. But the responsibility was not so much with Bozan, who sent the murderers, as with his master the sultan Barkiyaruq
