Overview

Al-Mustanjid billah, Yusuf ibn al-Muqtafi, an Abbasid caliph who ruled from 555 to 566 AH. 2

His caliphate

He lifted the taxes in Iraq and was severe on the corrupt. Al-Suyuti relates that he imprisoned a man who used to inform on people, and a man offered ten thousand dinars for him. He said to him: "I will give you ten thousand dinars and show me another like him, so I can imprison him and rid myself of his evil." 2

Ibn al-Najjar, as al-Suyuti quotes him, says he was described as having understanding, judgement and intelligence, had poetry and prose, and knowledge of making astronomical instruments and the astrolabe. 2

At the beginning of his caliphate al-Fa'iz, the ruler of Egypt, died, and al-Adid, the last of the Banu Ubayd caliphs, rose. 2

His death

He died on the eighth of Rabi al-Akhir 566 AH. 2

al-Mustadi bi-Amr Allah al-Hasan ibn al-Mustanjid

Abbasid caliph [566–575], born 536 to an Armenian umm walad; Ibn al-Jawzi: 'he proclaimed the lifting of tolls and the righting of wrongs, showed a justice and largesse we never saw in our days' — 1,300 silk robes cut in his first khil'a. In his reign the Ubaydid state ended and the khutba ran his name from Yemen to Aswan; he died at Shawwal's end, 575.
