Firishta's History (Gulshan-i Ibrāhīmī) 23.4.2

23.4.2

When Mahomed Ghoory was defeated, one of his officers named Zeeruk escaped from the field, and imagining his master was slain, made his way to Mooltan. Having waited on Ameer Daood Hussun, governor of the province, he told him that he had a private message from the king. Ameer Daood Hussun retired with him into his closet, where the assassin pretending to whisper into his ear, drew a dagger and stabbed him to the heart. He then ran instantly to the court-yard, where he proclaimed aloud, that he had killed the traitor Ameer Daood, in obedience to the King's command, and producing a false order, and commission, to assume the government, he was acknowledged by the army and the people.
