11.16.1

The fugitive amīrs stayed with Sultan Shams al-Dīn. Then Shams al-Dīn died and designated his son Shihāb al-Dīn as successor, who took his father's seat. Then his younger brother Ghiyāth al-Dīn Bahādur Būra — which in the Indian language means "the black" — overpowered him, seized the kingdom, and killed his brother Qutlū Khān and the rest of his brothers. Shihāb al-Dīn and Nāṣir al-Dīn fled from them to Tughluq, who set out in person with them to fight their brother, leaving his son Muḥammad as his deputy over his kingdom. He hastened to the land of Lakhnawtī, conquered it, captured its sultan Ghiyāth al-Dīn Bahādur, and brought him as a captive to his capital.
