al-Mustanjid bi'llah Yusuf ibn al-Muqtafi

Abbasid caliph [555–566]; he lifted Iraq's tolls and was hard on mischief-makers — to the man offering ten thousand dinars for a prisoner he answered 'take them, and show me another like him to jail'. Ibn al-Najjar praises his piercing mind and his craft of astrolabes and spheres. In his first year al-Adid, last of the Ubaydids, rose in Egypt; he died 8 Rabi' II 566.
