Muḥammad ibn al-Ḥusayn ibn Ibrāhīm ibn ʿĀṣim al-Sijistānī al-Āburrī—pronounced with a prolonged initial vowel followed by a ḍamma—is the author of The Merits of Imām al-Shāfiʿī. His nisba comes from the village of Ābur in the province of Sijistān.

He travelled in search of knowledge and heard ḥadith from the Imām of the Imams Ibn Khuzaymah, Abū al-ʿAbbās al-Thaqafī, Abū ʿArūbah al-Ḥarrānī, Makḥūl al-Bayrūtī, Muḥammad ibn Yūsuf al-Harawī, Abū Nuʿaym ibn ʿAdī al-Jurjānī, Muḥammad ibn al-Rabīʿ al-Jīzī, and the judge Zakariyyā ibn Aḥmad al-Balkhī.

Among those who narrated from him were Yaḥyā ibn ʿAmmār the preacher, ʿAlī ibn Bushrā al-Laythī, and others.

He died in Rajab 363 AH, and I think he was in his eighties.

Al-Āburrī said: Abū ʿArūbah narrated to us; Isḥāq ibn Zayd narrated to us; Muḥammad ibn al-Mubārak narrated to us; Yaḥyā ibn Ḥamzah narrated to me; al-ʿAlāʾ ibn al-Ḥārith narrated to me, from Makḥūl, from Jābir, who said, “I do not blame anyone for laying claim to his lineage on two occasions: when racing and when fighting. I say this because I saw the Messenger of Allah ﷺ let a horse run, and it won; he said, ‘It is like the sea!’ I also saw him strike with his sword and say, ‘Take it, for I am the son of the ʿAwātik,’ thus affiliating himself to his grandmothers.” (1)
