321 – al-Khurāsānī, ʿAbd Allāh ibn Isḥāq ibn Ibrāhīm
He was the shaykh, traditionist, and musnid: Abū Muḥammad ʿAbd Allāh ibn Isḥāq ibn Ibrāhīm ibn ʿAbd al-ʿAzīz al-Khurāsānī, al-Baghawī, later al-Baghdādī.
His grandfather was the brother of the Meccan ḥadīth scholar ʿAlī ibn ʿAbd al-ʿAzīz and the uncle of Abū al-Qāsim al-Baghawī.
He heard ḥadīth from ʿAbd al-Raḥmān ibn Muḥammad ibn Manṣūr Kurbazān, Yaḥyā ibn Abī Ṭālib, ʿAbd al-Malik ibn Muḥammad al-Raqāshī, Aḥmad ibn Milāʿib, Aḥmad ibn ʿUbayd ibn Nāṣiḥ, and many others.
He transmitted a great deal, and several well-known fascicles circulate from him.
Those who narrated from him include al-Dāraquṭnī, Ibn Mandah, al-Ḥākim, Ibn Razqawayh, Yaḥyā ibn Ibrāhīm al-Muzakkī, ʿUthmān ibn Dust, Abū ʿAlī ibn Shādhān, and others.
Hamzah al-Sahmī said: “I asked al-Dāraquṭnī about him, and he replied, ‘He is somewhat soft’ (1).”
I add: he died in the month of Rajab, in the year 349 AH.
