- Al-Iskāf ʿAbd al-Jabbār ibn ʿAlī ibn Muḥammad
The erudite scholar and master, Abū al-Qāsim ʿAbd al-Jabbār ibn ʿAlī ibn Muḥammad ibn Ḥaskān al-Isfarāyinī—nicknamed al-Aṣamm (“the Deaf”)—was a theologian better known as “al-Iskāf” (the Cobbler).
He studied under the eminent Abū Isḥāq al-Isfarāyinī and others, and he heard hadith from ʿAbd Allāh ibn Yūsuf al-Aṣbahānī along with a number of other authorities. Abū Saʿīd ibn Abī Nāṣir and others transmitted from him. Imām al-Ḥaramayn read the discipline of uṣūl (legal theory) under his tutelage.
Renowned for his God-fearing scrupulousness, constant devotion, worship, and asceticism, he was a prolific mufti and an outstanding exponent of the views of Abū al-Ḥasan al-Ashʿarī (1).
He passed away on the twenty-eighth of Ṣafar, 452 AH. Ibn ʿAsākir records his biography in Tabaqāt al-ʿUlamāʾ al-Ashʿariyyah (2).
