[Al-Būshanjī:] 227 [842] yilda Aḥmad ibn Ḥanbal Bag‘dodda ochiqdan-ochiq hadis dars bergan. Bu al-Mu‘tasim vafot etganidan keyin edi. Biz Kufada edik, xabarni eshitganimizda, Bag‘dodga qaytdim va o‘sha yilning rajab oyida, u hali dars berayotganida unga yetib oldim. Keyin sha‘bon oyiga uch kun qolganda u o‘z xohishi bilan to‘xtatdi. Hokimiyat unga to‘xtatishni buyurmagan edi, lekin o‘sha paytda Bag‘dodda qozi bo‘lgan al-Hasan ibn ‘Aliy ibn al-Ja‘d Ibn Abu Du’odga yozib, Ahmadning ochiqdan-ochiq hadis o‘qitayotganini xabar qilgan edi. Ahmad buni eshitgach, so‘ralmasdan to‘xtadi.

[Al-Būshanjī:] In ’27 [842], Aḥmad ibn Ḥanbal taught Hadith openly in Baghdad. That was right after al-Muʿtaṣim died. We were in Kufa when we heard the news. I headed back to Baghdad and caught up with him in Rajab of that year, while he was still teaching. Then, with three days left in Shaʿbān, he stopped of his own accord. The authorities hadn’t told him to stop, but al-Ḥasan ibn ʿAlī ibn al-Jaʿd, who was then judge in Baghdad, had written to Ibn Abī Duʾād to tell him that Aḥmad was openly teaching Hadith. When Aḥmad learned of this, he stopped without having to be asked.
