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

Al-Zahir bi-Amr Allah Abu Nasr Muhammad ibn al-Nasir, an Abbasid caliph who ruled between 622 and 623 AH. He was born in 571 AH and was given the caliphate at the age of fifty-two. ²

Al-Suyuti relates from Ibn al-Athir that at his accession he showed such justice and generosity that he restored the custom of the two Umars. He returned much of the wealth taken and the properties seized in his father's days. He abolished the dues and ordered the old land-tax restored; among this, the tax on Baqubba, from which eighty thousand dinars had been taken, was returned to ten thousand. ²

He released the people of the prisons, and on the night of the Feast of Sacrifice he distributed a hundred thousand dinars. He died on the thirteenth of Rajab 623 AH, so his caliphate lasted nine months and some days. ²
