Towards the end of his reign, Sultan Ula-ood-deen placed Ghazee Mulik, with 10,000 horse, in Daibulpoor, to expel the Moguls of Gungeez Khan. He had given to him (Ghazee Mulik) in Jageer, Mooltan, Ooch, and Sind: when the Sultan died he was there.

After the death of Sultan Ula-ood-deen, his sons, by their excessive neglect, indolence, and debauchery, did not turn their hearts to matters of state. On this account, disturbances found their way throughout the king­dom. At the time when neglect has become great, their wealth becomes small. So the wealth of the family of Ula fell. Kootb-ood-deen (the son of Ula-ood-deen) was of weak intellect. By some of his attendants, his head was cut off, at the instigation of Khusrow Khan, and he sat in his place on the throne. Khusrow Khan gave great honours to the Kafirs, and debauched men. He gave amongst these the treasuries of Sultan Ula-ood-deen and Kootb-ood-deen: on this account the Kafirs in Delhi became very strong, oppressing the Musulmans. Then Fakeer Mulik, secretly leaving Delhi, turned his face towards Mooltan. In a few days he got over the road, and finding his father, opened all the condition of Delhi to him. Ghazee Mulik and Fakeer Mulik were both brave men. To give assistance to Islam, and to take revenge on the Kafirs, they drew the sword of battle from the scabbard, and bound the girdle of war round the loins of their lives. They asked God for victory, and collecting the troops in Mooltan and Sind, they marched on Delhi. They arrived near it with 3,000 horse, all of whom had seen much service. When Khusrow Khan heard that they had come so near, collecting a large force, he sent it forth. The two bodies came in front of each other. The secrets of God are revealed!— that is to say, God gave the victory to Ghazee Mulik. The force of the Kafirs was beaten, and fled: many were killed; a few with great difficulty reached the fort. The following day Khusrow Khan, with a large force, went out, and drew up his men in battle array. The force of Ghazee Khan, to fight with their enemies, drew the sword of retaliation from the scabbard, and fought. In about one hour the army of the Kafirs was made grass by the sword of revenge; so much so, that the dead were in heaps. Khus­row Khan, with broken heart, turned his face in the direction of flight. Ghazee Mulik and Fakeer Mulik, from the field of battle, went near the city. At midnight, the governor of the town, the nobles, and the Kutwal, came and delivered the keys of the fort to Ghazee Mulik. The next morning he, with a large attendance, entered the city. In the Dewan Huzoor Sitoon he spread out the bedding of lamentation, in sorrow for Ula-ood-deen and Kootb-ood-deen. For three days he did this, agreeably to custom. He had it proclaimed in the town, that if any of the family of Ula-ood-deen or of Kootb-ood-deen were left and would come to him, he would place him on the throne; adding that he himself would bind the girdle of service round the loins of his life, and do service. After much inquiry, none being found, then the Ameers, the army, the Syuds, the men of letters, the priests, and all the people, agreed that Ghazee Mulik was worthy of the kingdom, because he had erased so many letters of dissension and trouble from the pages of the country, and he had given strength to Islam. In the year 720 (A. D. 1320), the title of Sultan Ghuyas-ood-deen Tughlug Shah was conferred on Ghazee Mulik. All the Ameers agreed to obey him. They placed him on the throne of the Sultanut of Delhi, and his name was read in the sermon. The title of Sultan Mahomed Shah was given to his son Fakeer Mulik. When Sultan Ghuyas-ood-deen left Mooltan to go to Delhi, the Soomrah tribe came and took Tatta. Sultan Ghuyas-ood-deen sent Mulik Taj-ood-deen to Mooltan, Khwaja Khuteer to Bukkur, and Mulik Ali Sher to Sehwistan.

In the year 723 (A. D. 1323), Sultan Ghuyas-ood-deen appointed his son Sultan Mahomed Shah as his heir, resigning the throne to him. He obtained from the Ameers a written deed, by which they agreed to be obedient to Sooltan Mahomed Shah. In the year 725 (A. D. 1324), the lamp of life of Ghuyas-ood-deen was blown out by the cold wind of death.
