Machine summary:
The importance of a deed of investiture from the Caliph cannot better be gauged than by the fact that Amr, who succeeded his brother Ya'qfib, was only given recognition as lawful ruler by the 'Ulama and the volunteers for the faith, when he had secured his patent of sovereignty from the Caliph ;1 and to gain public opinion Amr, on another occasion, exhibited the standard despatched from Baghdad in the court of his dwelling-house for three days at Nishapur.
" For these reasons, the Saffarids were obliged to come to terms with the Caliphate and ask for the confirmation of their claims over those territories which they had conquered even against the wishes of the Baghdad government ; and to continue the name of the Caliph in the khutbah and coinage even after they had come to a final breach with the central government, and were declared heretics and usurpers against the lawful government.
8 In accordance with the orders received from the Caliphate, the two prisoners were despatched to Baghdad and the messengers of the Samanids were sent back with robes and scented jewels for the governor of K.
3 In those provinces, of course, where the rulers were politically independent of the Buwayhids, the latter were not included in the khutbah, and only the name of the 'Abbasid Caliph was mentioned to signify the religious recognition of the institution.
