He traveled to Nishapur in 241 AH and related hadith there (1).
Al-Bukhārī, in his Ṣaḥīḥ—within the Book of the Military Campaigns—records a hadith from him (2), passed down through Aḥmad ibn Ḥanbal.
No definite date of death has been established for him (3). He journeyed far and wide and possessed exceptional breadth in the science of hadith (4).
57 – Aḥmad ibn al-Ḥasan ibn Khirāsh al-Baghdādī * (M, T)
The ḥāfiẓ and hadith scholar, Abū Jaʿfar al-Baghdādī.
He transmitted hadith from ʿAbd al-Raḥmān ibn Mahdī, Wahb ibn Jarīr, Shabābah ibn Sawwār, and their contemporaries.
Muslim and al-Tirmidhī cite him in their respective collections, as do Muḥammad ibn Hārūn ibn al-Mujaddar, Abū al-ʿAbbās ibn al-Sarrāj, and others.
He was deemed trustworthy (5).
(1) Tahdhib al-Tahdhib, 1:24, reports that he used to teach hadith in Maydan al-Husayn. Ibn Hajar cites Ibn Khuzayma’s appraisal: “He was one of the vessels of hadith.” Ibn Hibban likewise includes him among the trustworthy (al-Thiqat).
(2) Vol. 8, p. 116—the final narration in the section on the military campaigns—runs with its full chain: “Ahmad b. al-Hasan related to us; Ahmad b. Hanbal b. Hilal related to us; al-Mu‘tamar b. Sulayman, from Kahmas, from Ibn Buraida, from his father, who said: ‘He took part with the Messenger of Allah in sixteen expeditions.’”
(3) That is the date given here; in al-Tadhkira, 2:536, however, his death is placed in the year ‘a few and forty after two hundred’ (i.e., 244/858-9).
(4) Ibn Abi Hatim records in al-Jarh wa-l-Ta‘dil, 2:47: “When my father was asked about him, he said, ‘He is truthful (saduq).’”
