al-Zahir bi-Amr Allah Muhammad ibn al-Nasir

Abbasid caliph [622–623], fifty-two at accession — 'who opens a shop after asr, what does he earn?' Ibn al-Athir: 'he showed a justice that revived the way of the two Umars; had it been said none ruled after Umar ibn Abd al-Aziz like him, it were true' — confiscated estates returned, tolls lifted, Ba'quba's eighty thousand back to ten, the treasury's heavy weight denounced with 'Woe to the defrauders', a hundred thousand of wronged money restored. 'Treasuries are not made to fill but to be spent in God's way'. Nine months, dying 13 Rajab 623.
