Allāh al-Būshanjī, and a number of others. He kept company with al-Junayd and the senior masters; he travelled widely, lived in detachment, rose to prominence, and was considered reliable.

Those who narrated from him include al-Ḥākim, al-Sulamī, and Abū ʿAlī ibn Humshād.

Al-Sulamī said, “He is the most eminent shaykh we ever saw among the brethren and the earliest of them in companionship. He associated with al-Ḥakīm al-Tirmidhī and referred to various branches of knowledge.”

He died in 353 AH.

48 – Muḥammad ibn al-Ḥasan ibn al-Ḥusayn ibn Manṣūr al-Nīsābūrī *

The beneficial hadith master, the imam, the authoritative proof, Abū al-Ḥasan al-Nīsābūrī, a merchant and one of the notable scholars—just like his father and his uncle ʿAbdūs ibn al-Ḥusayn.

He heard hadith from Muḥammad ibn Ayyūb al-Rāzī, Abū ʿAbd Allāh al-Būshanjī, Muḥammad ibn ʿAmr Qashmarda, Abū ʿUmar al-Qattāt, Yūsuf al-Qāḍī, and their contemporaries in Khurāsān, the Jibāl region, and Iraq.

He gathered and compiled works, and was known for his honesty, precision, and generosity toward students. He authored a book patterned after that of the “Imam of the Imams,” Ibn Khuzaymah.

Al-Ḥākim mentioned him, praised him highly, and said, “I heard him say, ‘In my possession are more than a thousand fascicles transmitted from Ibn Nājiya and al-Qāsim al-Muṭarriz. In 315 AH I travelled to Bukhara, where people wrote down my narrations; even my father and my uncle transmitted from me.’”
