„That is also how Mahmud of Ghazni could enslave 500,000 “beautiful men and women” in Waihind after he had killed 15,000 fighting men in a “splendid action” in November 1001 C. E. Utbi informs us that Jaipal, the Hindu Shahiya king of Kabul, “his children and grandchildren, his nephews, and the chief men of his tribe, and his relatives, were taken prisoners, and being strongly bound with ropes, were carried before the Sultan (Mahmud) like common evil-doers… Some had their arms forcibly tied behind their backs, some were seized by the cheek, some were driven by blows on their neck.”“
— Jayapala Ruler of the Kabal Shabi 964 - 1001
In every campaign of Mahmud large-scale massacres preceded enslavement.
