The mountain chief would tolerate no rival near his throne. Hearing that one Aboo Hashem, a descendant of Ali, had arrogated to himself the dignity of imam in the province of Ghilan, which lies north of Kuhistan, and had issued letters calling on the people to acknowledge him, Keäh wrote to him to desist from his pretensions. The self-appointed imam only replied by reviling the odious tenets of the Ismaïlites. The sheikh forthwith sent a body of his troops against him, took him prisoner, and, after trying him by a court-martial, committed him to the flames. Though, as we have seen, the settlements of the Assassins were in the mountainous region of Irak, in the north-west of Persia, their power was of such a nature that no distance was a security against it. A Fedavee could speedily traverse the intervening regions to plant his dagger in the bosom of any prince or minister who had incurred the vengeance of the Sheikh-al-Jebal. Accordingly we find the shah (_King_) of Khaurism, between which and Irak lies the extensive province of Khorasan, coming to Sultan Massood, the successor of Mahmood, to concert with him a plan for the destruction of these formidable foes to princes. The shah of Khaurism had been formerly rather disposed to favour the Ismaïlites, but his eyes were now opened, and he was become their most inveterate enemy. Sultan Massood, we know not for what reason, bestowed on him the lands which Berenkesh, the grand falconer, had held of the sultan. Berenkesh, mortally offended at this unworthy treatment, retired, with his family, to the territory of the Ismaïlites, and sought the protection of Keäh, whose open enemy he had hitherto been. Policy, or a regard to good faith and humanity, made the Assassin prince grant the protection which was required; and when the shah of Khaurism wrote, reminding Keäh of his own former friendship, and the bitter hostility of Berenkesh, and requesting him, on that plea, to give up the fugitive, the sheikh replied, "The shah of Khaurism speaks true, but we will never give up our suppliants." Long and bloody enmity between the sheikh and the shah was the consequence of this refusal to violate the rights of hospitality.
