Last writing of Muhammad ibn az Zaiyat

Letter to Caliph: "Such is the way of earthly things; from day to day they fleet on and pass away, as visions seen in sleep. Cease repining! Such events are the vicissitudes which fortune transmits from man to man"

Scrawled on the side of the torture cage: "Let him who knows where sleep is to be found direct toward it one who longs for it. May God have mercy on the compassionate man who will lead sleep to my eyes! I wake, but he sleeps by whom I am despised"
