I add: and likewise Abū Muʿāwiyah and Ibn ʿUyaynah.
Mūsā ibn Muʿāwiyah said: “I never met anyone more prolific in transmission than Wakīʿ. He narrated thirty-five thousand hadiths, and he recited them to us aloud, in the very order he had compiled, without wavering over a single report.”
He also related: “I left Qayrawān convinced that no one was more humble than Bahlūl ibn Rāshid—until I met Wakīʿ. During Ramadan he would complete one full khatma of the Qurʾān and a third more during the night (1). He performed twelve rakʿahs of the forenoon (duḥā) prayer and kept praying from the noon (ẓuhr) prayer until the afternoon (ʿaṣr).”
Mūsā further said: “The Caliph Hārūn led us in the dawn prayer in the Sacred Mosque. He recited Sūrat al-Raḥmān and al-Wāqiʿah, and I wished he would never fall silent, so beautiful was his recitation. Later I went to al-Fuḍayl and heard him say, ‘Poor Hārūn! He recited al-Raḥmān and al-Wāqiʿah without knowing what they contain.’”
Those who narrated from Mūsā include Muḥammad ibn Waḍḍāḥ, Abū Sahl Furāt, Muḥammad ibn Sahnūn, and others.
Ibn Waḍḍāḥ said: “He is reliable and possesses an abundance of hadiths. He travelled to Kūfah and Rayy; I met him in Qayrawān.”
Muḥammad ibn Aḥmad al-ʿAnsi stated: “He is Mūsā ibn Muʿāwiyah ibn Ṣumādih ibn ʿAwn ibn ʿAbd Allāh ibn Jaʿfar ibn Abī Ṭālib, a descendant of the Ṭālibids. I met him after he had lost his sight.”
Thus, everything in al-Mudawwana that is attributed to Wakīʿ or Ibn Mahdī actually reached Sahnūn through Mūsā.
