133 – Mujāhid ibn Mūsā ibn Farrukh al-Khwarizmi * (M, T, S, Q, D)
A ḥāfiẓ, an imām, and an ascetic—Abū ʿAlī al-Khwarizmi, long-time resident of Baghdad.

He transmitted hadith from Hushaym, Abū Bakr ibn ʿAyyāsh, Sufyān ibn ʿUyaynah, al-Walīd ibn Muslim, Ismāʿīl ibn ʿUlayyah, and others of their rank.

Those who narrated from him include the compilers of the Five Books—everyone except al-Bukhārī—as well as Abū Zurʿah al-Rāzī, Abū Ḥātim, Ibrāhīm al-Ḥarbī, Mūsā ibn Hārūn, Abū Yaʿlā al-Mawṣilī, Abū al-Qāsim al-Baghawī, and a number of others.

Aḥmad ibn Muḥammad ibn Muḥriz reported from Yaḥyā ibn Maʿīn, who said: “He is trustworthy; there is nothing objectionable about him.”

Mūsā ibn Hārūn said, “He was six years older than Aḥmad ibn Ḥanbal.”

Al-Khaṭīb said: I read in the book of ʿUbayd Allāh ibn Jaʿfar:
“Abū Yaʿlā al-Ṭūsī narrated to us; Muḥammad ibn al-Qāsim al-Azdī narrated to us; he said:
‘Mujāhid ibn Mūsā told us—and whenever he finished transmitting a narration he would either throw the original into the Tigris or wash it away. One day he arrived carrying a tray and said, “This is all that remains, and I do not think you will see me after today.” He then narrated its contents, cast it away, and died shortly thereafter—may Allah Most High have mercy on him.’”
