He then devoted a lengthy chapter to the foods and remedies mentioned by the Prophet, peace and blessings be upon him, arranging them in alphabetical (alif-bāʾ) order, unlike medical works, which generally use the traditional abjad order. In this section he also mentioned spiritual remedies, such as prayer, patience, the Quran, and recitations for healing.
These chapters also contain discussions and valuable observations concerning monotheism, Quranic exegesis, hadith, and jurisprudence. Examples include his reconciliation of the denial of contagion with the command to flee from a leper (4/ 55 - 60); his discussion of the legal implications of the hadiths concerning cupping and its effect on the fast (4/ 83 - 84); the permissibility of silk for men because of a need or an overriding benefit (4/ 106 - 108); the special significance given to the number seven in divine decree and religious law (4/ 136 - 139); his explanation of the subtle wisdom behind not seeking a cure through forbidden substances (4/ 225 - 226); and his refutation of those who deny the harmful effects of the evil eye (4/ 233 - 235). As for his outstanding discussion of the purification of souls and the healing of hearts, one need only consult the chapter he devoted to the Prophet’s guidance, peace and blessings be upon him, in treating distress, worry, anguish, and sorrow, and explaining the basis of the spiritual remedies mentioned in the hadiths (4/ 282 - 301).
In most of these medical chapters, the author—may Allah have mercy on him—relied on the book of ʿAlāʾ al-Dīn al-Kahhāl al-Hamawī, as will be discussed below. Consequently, he reproduced errors from that book in references to hadith sources and in their wording. Nor did he confine himself to authentic hadiths: he also discussed individual medicinal substances concerning which no authentic hadith from the Prophet, peace and blessings be upon him, exists, and which therefore have no connection with prophetic medicine, such as aubergine, celery, and leek. He explicitly stated that the three hadiths concerning them were fabricated, yet nevertheless described their properties and benefits (4/ 596 - 598).
