The shaykh, musnid, and reliable authority; the hadith scholar of Samarqand, Abū Jaʿfar Muḥammad ibn Muḥammad ibn ʿAbd Allāh ibn Ḥamzah ibn Jamīl al-Baghdādī, better known as al-Jammāl.
He settled in Samarqand and there narrated extensively from Abū Bakr ibn Abī al-Dunyā, Aḥmad ibn ʿAbd Allāh al-Narsī, Jaʿfar ibn Muḥammad ibn Shākir, ʿAbd al-Karīm ibn al-Haytham, and their colleagues in his native land.
Later he travelled—he used to journey for commerce—and in Damascus heard hadith from Abū Zurʿah al-Naṣrī and others; in Egypt from Abū ʿUlāthah Muḥammad ibn ʿAmr, Yaḥyā ibn ʿUthmān ibn Ṣāliḥ, and Khayr ibn ʿArafah; and in Yemen from ʿUbayd al-Kashwarī and al-Dabarī, gathering original manuscripts along the way.
