say: “Abū Isḥāq has two hundred hadiths whose chains run exclusively through him.”
I also heard ʿAllān al-Kurjī relate from Abū Ḥātim that the figure was five hundred hadiths.

Abū Aḥmad al-Qaṣṣāb said, “I have never seen anyone like Ibn Yaʿqūb; with him I found material I had not encountered with anyone, neither in Baghdad nor in Isfahān.”

Ṣāliḥ gives a lengthy biography of him and records that he refused to transmit from Ibrāhīm ibn Naṣr because some people had criticized the latter.

He died in 325 AH.

Al-Khalīlī stated: “My grandfather and Muḥammad ibn Isḥāq al-Kaysānī narrated from him and considered him reliable.”

I (the author) add: Among those who narrated from him were Aḥmad ibn Firās al-ʿAbqasī and Ṣāliḥ ibn Aḥmad; he was trustworthy.

214 – al-Maydānī, Abū ʿAlī Muḥammad ibn Aḥmad ibn Muḥammad *
The shaykh and truthful transmitter, Abū ʿAlī Muḥammad ibn Aḥmad ibn Muḥammad ibn Maʿqil al-Naysābūrī al-Maydānī, hailed from a district of Nīshāpūr known as Maydān Ibn Ziyād.

He heard a single fascicle from Muḥammad ibn Yaḥyā al-Dhuhlī—the very copy now in the keeping of Sibt al-Silafī.

Those who narrated from him include Abū Saʿīd ibn Abī Bakr, Abū ʿAbd Allāh ibn Mandah, Abū Ṭāhir ibn Maḥmish, Abū Bakr al-Ḥīrī, and others.
