Firishta's History (Gulshan-i Ibrāhīmī) 23.2.2

23.2.2

On the accession of Gheias-ood-Deen to the throne of Ghizny and Ghoor, he appointed his brother, Moyiz-ood-Deen Mahomed, governor of Tukeeabad: the latter continued from that period to make incursions upon Ghizny, which had reverted into the hands of some of the descendants of the house of Subooktugeen. In the year A. D. 1171, Gheias-ood-Deen marched in person against the officers of Sooltan Khoosrow Muilik, the last of the Ghiznevides, and recovered Ghizny from them. He gave the government to his brother Mahomed, who in the year A. D. 1176 led an army towards Mooltan, and having subdued that province, marched to Oocha. The Raja was besieged in his fort; but Mahomed Ghoory, finding it would be difficult to reduce the place, sent a private message to the Raja's wife, promising to marry her if she would deliver up her husband. The base woman returned for answer, that she was rather too old herself to think of matrimony; but that she had a beautiful and young daughter, whom if he would promise to espouse, and leave her in free possession of her wealth, she would in a few days remove the Raja. Mahomed Ghoory accepted the proposal; and this Princess, in a few days, found means to assassinate her husband, and to open the gates to the enemy.
