The Life Of Ibn Hanbal by Ibn Al-Jawzi

[Al-Būshanjī:] During the funeral prayers for Aḥmad ibn Ḥanbal, some of the mourners cursed al-Karābīsī openly. The cursing was reported to al-Mutawakkil, who asked who he was. Told that al-Karābīsī had invented a doctrine previously unknown, he ordered him confined to his house until he died. 84.1

[Al-Nasawī:] I attended Aḥmad ibn Ḥanbal’s funeral. It was very crowded. Al- Karābīsī was cursed loud and long, as was al-Marīsī. 84.2

[Al-Warrāq:] At Aḥmad ibn Ḥanbal’s funeral, the mourners made an open display of adherence to the sunnah and cursed the purveyors of reprehensible innovation. By showing them the ascendancy and might of Islam as well as the suppression of errant guides, dissenters, and reprehensible innovators, God consoled the Muslims for the calamity they had suffered. Some mourners camped out at the gravesite, and women began to visit as well. The authorities accordingly sent patrolmen to clear the area and restore order. 84.3

[ʿAlī ibn Mahruwayh’s aunt:] On the day Ibn Ḥanbal died, the only place in Baghdad where the afternoon prayer was performed was Ḥārith’s mosque. 84.4
