Firishta's History (Gulshan-i Ibrāhīmī) 6.1.7

6.1.7

Elik Khan, ruler of Kashghar, seizing the opportunity afforded by these dissensions, marched from Kashghar to Bokhara, and slaying Abool Mullik, annihilated his whole race. Thus the house of Samany, which had continued to reign in Bokhara for a period of one hundred and twenty-eight years, became extinct. Mahmood, at this juncture, employed himself in settling the government of the provinces of Bulkh and Khorassan, which he regulated in such a manner, that his fame reached the Caliph of Bagdad, Alkadir-Billa of the house of Abaas; who sent him a rich honorary dress (such as he had never before bestowed on any king), and dignified Mahmood with the titles of Ameen-ool-Millut, and Yemeen-ood-Dowlut. In the end of the month Zeckad, in the year 390, Mahmood proceeded from Bulkh to Hirat, and thence to Seestan, where having defeated Khuluf the son of Ahmed, the governor of that province, he returned to Ghizny. About the same time, also, he marched in the direction of India, took many forts and provinces, in which having established his own governors, he returned to his capital. Having overcome all opposition to his government, he devoted himself for some time to the improvement of his country and to the organisation of courts of civil and criminal justice.
