For the Mu’assasat Āl al-Bayt, a copy of it exists in the Leipzig Library, 13 [17](1).

Our companion and beloved Dr. Muhammad ibn Lutfi al-Sabbagh, may Allah preserve him, erred in thinking that its manuscript is preserved in the Laleli Library in four volumes, under the numbers (498–501)(2), because these volumes, according to the comprehensive index of the Mu’assasat Āl al-Bayt(3), belong to Ahmad ibn al-Husayn ibn Arslan al-Ramli, who will be mentioned later, Allah willing.

6 — The commentary of al-Hafiz Abu Zur‘ah Wali al-Din Ahmad ibn ‘Abd al-Rahim ibn al-Husayn al-‘Iraqi, who died in the year (826 AH), and he is the son of al-Hafiz Zayn al-Din al-‘Iraqi. Al-Hafiz Ibn Hajar said: He began the “Commentary on the Sunan” of Abu Dawud and wrote approximately one-sixth of it in seven volumes in draft form(4). Al-Hafiz al-Suyuti said: It is a very extensive commentary upon it; he wrote from its beginning to the prostration of forgetfulness in seven volumes, and he wrote a volume containing fasting, pilgrimage, and jihad. Had he completed it, it would have come to more than forty volumes(5).

According to the comprehensive index of the Mu’assasat Āl al-Bayt, a copy of the fourth volume exists in the Saddam House, 181 [12474], in (218 folios), lacking its end(6).
