Judge Abū al-Qāsim Aḥmad ibn Yazīd ibn Baqī al-Mālikī—through a public reading to him in 620 AH—said:
“Muḥammad ibn ʿAbd al-Ḥaqq al-Qurṭubī informed us by recitation; he said:
‘Imam Muḥammad ibn Faraj, the client of Ibn al-Ṭallāʿ, informed us; he said:
“Judge Abū al-Walīd Yūnus ibn ʿAbd Allāh ibn Mughīth informed us by direct audition.
He was in turn informed by Abū ʿĪsā Yaḥyā ibn ʿAbd Allāh ibn Yaḥyā ibn Yaḥyā ibn Yaḥyā al-Laythī through recitation—he died in Rajab 367 AH—who said:
‘The jurist’s great-uncle, Abū Marwān ʿUbayd Allāh ibn Yaḥyā ibn Yaḥyā—he died in Ramaḍān 298 AH—informed us; he said:
“My father informed us, saying: ‘Mālik ibn Anas narrated the work to us—save for the portion he had missed on iʿtikāf (spiritual retreat)—and thus he related the entire Muwaṭṭaʾ.’ ” ’ ”
169 – Abū al-Jahm al-ʿAlāʾ ibn Mūsā ibn ʿAṭiyya al-Bāhilī
The shaykh, ḥadith scholar, and reliable transmitter: Abū al-Jahm al-ʿAlāʾ ibn Mūsā ibn ʿAṭiyya al-Bāhilī of Baghdad, the holder of that renowned high-isnād booklet. I mention him here, as I have other exceptionally long-lived narrators, for the fame he enjoyed; I do not claim to have catalogued them all.
He heard ḥadith from ʿAbd al-ʿAzīz ibn al-Mājishūn—one report whose chain he later forgot—as well as from Layth ibn Saʿd, Sawwār ibn Muṣʿab, ʿAbd al-Quddūs (apparently Ibn Ḥabīb), Sufyān ibn ʿUyayna, Haytham ibn ʿAdī, and others.
Those who transmitted from him include Isḥāq ibn Sunayn al-Khuṭṭalī, Aḥmad ibn ʿAlī al-Abbār, and Abū al-Qāsim al-Baghawī.
