Firishta's History (Gulshan-i Ibrāhīmī) 23.2.5

23.2.5

In the year 580, he again invaded Lahore, where Khoosrow Mullik, shutting himself up in the fort, as before, sustained a long siege, from which Mahomed was at length compelled to desist. In this expedition he repaired the fort of Sealkote, wherein he left a garrison to command the countries between the rivers Ravy and Chunab, placed by him under the government of Hoossein Firmully, while he himself retired to Ghizny. This fort, as we have before related, being successfully besieged, and taken by Khoosrow Mullik, occasioned the third expedition of Mahomed Ghoory to Lahore, of which he made himself master in the year 582, by the stratagem mentioned in the conclusion of the history of Ghizny. He sent Khoosrow Mullik and his family prisoners to his brother Sooltan Gheias-ood-deen at Feroozkooh, who confined them in a fort in Joorjistan, where they were some time after put to death, during the subsequent war with Khwaruzm Shah, and the dynasty of Ghizny then became wholly extinct. Mahomed Ghoory, having settled the province of Lahore, confided the government to Ally Kirmany, governor of Mooltan, and retired to Ghizny. In the year 587, he marched again to Hindoostan, and proceeding towards Ajmeere, he took the town of Bituhnda, where he left Mullik Zea-ood-Deen Tooluky with above a thousand chosen horse, and some foot to form its garrison.
