On the 16th of Rumzan, 792 (A. D. 1389), he became Sultan. The first thing he did was to turn out of the city all the attendants and slaves of Pheroz Shah, who had been his enemies. He killed many, proclaiming, that if any of them remained in the city, his blood would be upon his own neck. He entered the city with great state, taking much care of the country and property. When he had attained great power, it came across him that it was not fit to neglect Aboo Bukur, therefore he sent his youngest son, Hoomayoon Khan, with many Ameers, and a large force against him. When these got near Kotulah, where Aboo Bukur Shah remained, Bahadoor Khan Nahur, who was born in the house of Pheroz Shah (by whose assistance Aboo Bukur had col­lected many men), fell upon the troops of Hoomayoon by night, but Aboo Bukur, being defeated, retreated to the fort of Kotulah. When Sultan Mahomed Shah heard of this, he went there by forced marches, and surrounded the fort. Then Aboo Bukur Shah, being helpless, asked for pardon. Sultan Mahomed confined him in the fort of Mewat, where he died. Sultan Mahomed went to Delhi, then to Guzerat; from thence to Bengal, where he stayed a long time, punishing the evil doers and disturbers of the peace. He remained at Mahomedabad, a fort built in his time. After a time he fell sick, when Bahadoor Khan Nahur looted some villages near Delhi. The Sultan, hearing of this, though unwell, marched towards Mewat. When he drew near Kotulah, Bahadoor Khan came forth to meet him. He was defeated, and took refuge in Kotulah, but not having strength, he fled. The Sultan then returned to Maho­medabad, to see some works which he had in hand. His sickness increased, and on the 17th of Rubee-ool-Awul, 796 (A. D. 1393), he went to heaven. He reigned six years and seven months.
