The Strife over Declaring the Hanbalis Unbelievers and the Looting of the Nizamiyya Market

In 470 Nizam al-Mulk's letter reached Abu Ishaq al-Shirazi rebuking the anti-Hanbali agitation in his own Nizamiyya: 'Sultan's policy and the rule of justice oblige us to lean to no madhhab over another; we did not build this school but to shelter the people of learning — not to split the community — and the madhhab that dominates Baghdad and its quarters is that of the imam Ahmad ibn Hanbal.' The Hanbalis circulated it and were strengthened. Then on Tuesday 2 Shawwal a madrasa student called al-Iskandarani went to Suq al-Thulatha pronouncing the Hanbalis unbelievers; pelted with a brick he fled back to the madrasa market, whose men sallied out and looted the other market — until the mob reversed it, burst into the madrasa market, plundered their quarter and killed a sick man in his room. The Daylamite guards shot dead some fifteen, and the bodies were carried to the diwan for the qadis and witnesses to attest.
