al-Mustansir bi'llah Mansur ibn al-Zahir

Abbasid caliph [623–640], hailed Rajab 623; builder of the Mustansiriyya — four madhhab chairs, bimaristan, kitchen, hammam, 70,000-mithqal waqf. His host once routed the Tatars; in 632 he struck silver dirhams to spare people usurious gold-cutting. His fierce brother al-Khafaji was passed over for his mild son Ahmad.
