Firishta's History (Gulshan-i Ibrāhīmī) 23.4.4

23.4.4

During the residence of Mahomed Ghoory at Lahore, on this occasion, the Gukkurs, who inhabited the country along the banks of the Nilab, up to the foot of the mountains of Sewalik, exercised unheard of cruelties on the Mahomedans, and cut off the communication between the provinces of Pishawur and Mooltan. These Gukkurs were a race of wild barbarians, without either religion or morality. It was a custom among them as soon as a female child was born to carry her to the door of the house, and there proclaim aloud, holding the child in one hand, and a knife in the other, that any person who wanted a wife might now take her, otherwise she was immediately put to death. By this means, they had more men than women, which occasioned the custom of several husbands to one wife. When this wife was visited by one of her husbands, she left a mark at the door, which being observed by any of the other husbands, he withdrew till the signal was taken away. This barbarous people continued to make incursions on the Mahomedans till in the latter end of this King's reign, their chieftain was converted to the true faith when a captive. After becoming a proselyte he procured his release from the King, who endeavoured to persuade him to convert his followers, and at the same time honoured him with a title and dress, and confirmed him in the title of chief of the mountains.
