When Caliph Al-Mutawakkil had been killed in 861, jurists had retroactively validated his murder with a fatwa. Eight years later, they had testified to the lawful abdication of a successor, after he had been dragged from a toilet, beaten unconscious, and thrown into a vault to die. By the middle of the tenth century, judges were solemnly confirming that the onset of blindness had disqualified a caliph, without mentioning that they had just been assembled to witness the gouging of his eyes.
