al-Ḥasan ʿAbd al-Raḥmān ibn Muḥammad ibn al-Muẓaffar ibn Muḥammad ibn Dāwūd ibn Aḥmad ibn Muʿādh al-Dāwūdī, the Būshanjī (1).

He was born in Rabīʿ al-Ākhir, 374 AH.

He heard the Ṣaḥīḥ, the Musnad of ʿAbd ibn Ḥumayd together with its Qur’anic commentary, and the Musnad of Abū Muḥammad al-Dārimī from Abū Muḥammad ibn Ḥammwayh al-Sarkhasī in Būshanj, and in the loftiness of that isnād he stood unrivalled in the world.

At Herat he heard from ʿAbd al-Raḥmān ibn Abī Shurayḥ.

At Nīshābūr he heard from Abū ʿAbd Allah al-Ḥākim, Ibn Yūsuf, and Ibn Maḥmish.

In Baghdad he heard from Ibn al-Ṣalt al-Mujbir, Ibn Mahdī al-Fārisī, and ʿAlī ibn ʿUmar al-Tammār.

He first came to Baghdad in 399 AH, remained there for several years, and studied jurisprudence under Abū Ḥāmid, Abū al-Ṭayyib al-Ṣuʿlūkī, Abū Bakr al-Qaffāl, and Ibn Maḥmish.

It is said that he lived on what was sent to him from an estate he owned in Būshanj, that he was extraordinarily scrupulous, and that his virtues were many.

Abū Saʿd al-Samʿānī said: “He was the foremost of the shaykhs of Khurasan—let alone within his own province—renowned for his lineage, his excellence, and his way. His footing in God-fearingness was firm; leagues (farāsikh) deserved to be crossed for the blessing of his company. His mastery of the disciplines was famous, his name is inscribed in the books, his days were radiant, and his words were pearls. He studied literature with Abū ʿAlī al-Fanjukirdī (2) and jurisprudence.”
