Firishta's History (Gulshan-i Ibrāhīmī) 23.3.4

23.3.4

Mahomed Ghoory in person went to Ajmeer, of which he also took possession, after having put some thousands of the inhabitants, who opposed him, to the sword, reserving the rest for slavery. Afterwards, on a promise of a punctual payment of a large tribute, he delivered over the country of Ajmeer to the Gola, or natural son, of Pithow Ray. He now turned his arms towards Dehly; but was prevailed on by the new king, with great presents, not to prosecute the war further. On this occasion he left his faithful slave and friend, Mullik Kootb-ood-Deen Eibuk, in the town of Kohram, with a considerable detachment, and marched himself with the body of his army towards the mountains of Sewalik, which lie to the north of India, destroying and plundering the countries on his retreat towards Ghizny. After the return of Mahomed Ghoory, his General, Mullik Kootb-ood-Deen Eibuk, took the fort of Merut and the city of Dehly from the family of Chawund Ray; and it is owing to this circumstance that foreign nations say, "The empire of Dehly was founded by a slave." In the year 589 he also took the fort of Kole; and making Dehly the seat of his government, established himself there, and compelled all the districts around to acknowledge the faith of Islam.
