Khazaʾin al-futuh 6: Invasion under Ikbal Mudhir, and Muddhir Tái Balwí.

6

"Another army, namely, that of Ikbál Mudbir and Mudabir Tái Balwí, followed close behind Kapak's, thirsty for the blood of the Musulmáns, but well filled with the blood of their own tribes. Suddenly a torrent of blood of the slaughtered infidels flowed towards them," and they had no place to stand on. "Meanwhile, the van of the army of Islám advanced like clouds and rain against them, and fell like a raging storm on those Jahánnamís." Both these leaders were compelled to fly across the river of Sind. Ikbál was taken prisoner, with many of his followers, and those who escaped fled towards the north, and "countless infidels were despatched to hell." A farmán was issued by Sultán 'Aláu-d dín that the surviving prisoners should be massacred, and beaten up into mortar for the fort.
'They hung down from the Taikrí and Chíní fortress, As Abyssinians with heads inverted hang from a new building;'
And a bastion was formed from an hundred thousand of their heads."
