Those who devoted themselves to "Sunan Ibn Mājah"

The people of knowledge devoted themselves to Ibn Mājah's book in transmission and understanding, in commentary and annotation, in discussion of its narrators, and in extracting its additional narrations (zawāʾid).

1. The erudite scholar, the jurist, the grammarian, the physician, the master of many disciplines, Muwaffaq al-Dīn Abū Muḥammad ʿAbd al-Laṭīf ibn al-Faqīh Yūsuf ibn Muḥammad ibn ʿAlī al-Mawṣilī al-Baghdādī al-Shāfiʿī, resident of Aleppo, who died in the year (629 AH) (1), wrote a commentary on it. It is an extensive commentary, as is understood from the "Arbaʿūn Ṭibbiyya" of al-Birzālī.

2. The "Arbaʿūn Ṭibbiyya" (Forty Medical Hadiths) was extracted by the ḥāfiẓ Zaki al-Dīn Muḥammad ibn Yūsuf al-Birzālī, who died in the year (636 AH) (2), from "Sunan Ibn Mājah" and from its commentary by the erudite scholar ʿAbd al-Laṭīf al-Baghdādī. It was first printed in Morocco, then printed in Beirut. Its introduction states: Its author Muḥammad ibn Yūsuf al-Birzālī says: When I departed from Mecca—may Allah honor it—on the Wednesday stop, I headed for Syria for the sake of "Sunan Ibn Mājah." I met the Shaykh Abū Muḥammad ʿAbd al-Laṭīf ibn Yūsuf ibn Muḥammad al-Baghdādī—may Allah preserve him—and I was informed that it was his transmission. I asked him to let me read it to him, and he graciously agreed. I began reading it, and when I reached the chapters on medicine, I asked him to clarify for me its difficult passages and to explain to me the noble knowledge and the lofty, subtle wisdoms it contained. He graciously agreed.
