Ahraf Ghani evidently didn't want to meet the same fate as Mohammad Najibullah

[DemocratSinceBirth]

Najibullah was at the UN compound when the Taliban soldiers came for him on the evening of 26 September 1996.[7] The Taliban abducted him from UN custody and tortured him to death, and then dragged his dead (and, according to Robert Parry, castrated[77]) body behind a truck through the streets of Kabul. His brother, Shahpur Ahmadzai, was given the same treatment.[78] Najibullah and Shahpur's bodies were hanged from a traffic light pole outside the Arg presidential palace the next day in order to show the public that a new era had begun. The Taliban prevented Islamic funeral prayers for Najibullah and Shahpur in Kabul, but the bodies were later handed over to the International Committee of the Red Cross who in turn sent their bodies to Gardez in Paktia Province, where both of them were buried after the Islamic funeral prayers for them by their fellow Ahmadzai tribesmen.[78]
