Read up on Kenana ibn al-Rabi sometime. Almost makes the Aisha stuff seem tame.

Moe invades a city, they repeal him, he announces that Allah really wants him to attack a small farming town instead. He does. He becomes convinced that there was some hidden money so orders Kenana tortured, then executed. While his headless body was still on the ground he grabs his widow and when told that she was already war spoil traded her for seven slaves.
