al-Islām Ibn Taymiyya, as established by Dr. ‘Abd al-Hakīm al-Anīs in an article published on the Alukah website.

• Other sources from which he quoted without acknowledgment include “Laqt al-Manāfi‘” by Ibn al-Jawzī, “Minhāj al-Bayān” by Ibn Jazla, and “Al-Mūjaz” by Ibn al-Nafīs. As for his statement in the discussion of clothing, “The author of Al-Minhāj said,” the entire passage was taken from that author through al-Hamawī’s book. Ibn al-Qayyim also consulted another medical source that we have not located, drawing from it the types of evacuation, the causes of vomiting, and other material.

• He also quoted from Ibn al-Sunnī’s book in the entry on “clarified butter.” This material does not appear in al-Hamawī’s book, so I do not know whether he quoted it directly or through an intermediary.

• His oral sources include “one of the highly skilled physicians” (4/ 186), from whom he related an account concerning the physician’s sister’s son and kohl. He also related it in his two books, “Al-Turuq al-Hukmiyya” (2/ 738) and “Tuhfat al-Mawdūd” (p. 400). His wording in the latter is: “The chief physician in Egypt told me.”

• Sources for the fifth and sixth volumes:

In matters of jurisprudence, he relied chiefly on “Al-Mughnī,” “Al-Muhallā,” and works belonging to the various legal schools. We have therefore combined the two volumes in the following list of their principal sources:
