Firishta's History (Gulshan-i Ibrāhīmī) 38.2.7

38.2.7

The guards started up in confusion, but were instantly attacked by the conspirators, and massacred before they could prepare for defence. The King, alarmed at the noise, asked Mullik Khoosrow, who lay in his apartment, the cause. The villain arose as if to enquire, and going out on the terrace, stood for some time, and returning, told the King, that some of the horses belonging to the guard had broken loose and were fighting, while the people were endeavouring to secure them. This satisfied Moobarik for the present, but soon after, the conspirators ascended the stairs and got upon the terraces which led to the royal sleeping apartment. Here they were stopped by Ibrahim and Isaac, two servants, as well as by the sentries over the private chambers, all of whom were immediately put to the sword. The King hearing the clash of arms, and the groans of dying men so near, arose up in great alarm, and ran towards the haram, by a private passage. At this moment Mullik Khoosrow, fearing he might escape, rushed after him, and seizing him by the hair in the gallery, struggled with him for some time. Moobarik, being the stronger man, threw Khoosrow on the ground: but as Khoosrow had twisted his hand in the King's hair, the latter could by no means disengage himself, till some of the other conspirators came, and with a stroke of a scimitar cut off the King's head, and threw it into the court-yard.
