88.2.9

In the year 901, Dustoor Deenar, the Abyssinian eunuch, who held the districts of Koolburga, Sagur, Alund, and other forts and districts between the river Beema and Tulingana, aspired to establish his independence. For this purpose he opened a communication with Mullik Ahmud Bheiry; observing, that as Futteh Oolla Imad-ool-Moolk had, in concert with Yoosoof Adil Shah, assumed royal titles in Berar, it would be consistent with his friendship to support him in doing the same. Dustoor Deenar was the adopted son of Nizam-ool-Moolk, the father of Mullik Ahmud Bheiry, and thought, in consequence, he had claims on his support. Accordingly the eunuch, having adopted the regal canopy, seized many districts dependent on the capital of Ahmudabad Bidur, and expelled the officers of Kasim Bereed.
