Ibn Majah

Benefits and Issues:

➊ "Mann" is the name of that natural food which was sent down upon the Children of Israel. It used to come in the form of sweet grains. Those people would take and use it as needed.

➋ Mushroom is called "mann" because it is also obtained without any effort.

➌ There are many types of mushrooms, some of which are edible and some are harmful. "Kamāh" is among the beneficial types. Nowadays, beneficial types of mushrooms are cultivated, which are used as food.

➍ Regarding the use of mushroom water for eye diseases, some scholars have said that it should be used mixed with another medicine. For example, the water of mushroom can be mixed and kneaded with "ithmid" (antimony) kohl, and then applied to the eye. According to the opinion of some scholars, its water should be extracted and used alone. (Zād al-Ma‘ād) The correct view seems to be that, with the advice of physicians, it should be used in different appropriate ways for various eye diseases.

➎ There is a hadith of similar meaning regarding "‘ajwah" (dates) in Sahih al-Bukhari, the words of which are: "Whoever eats seven ‘ajwah dates in the morning, on that day no poison or magic will harm him." (Sahih al-Bukhari, Book of Medicine, Chapter: The Remedy with ‘Ajwah against Magic, Hadith: 5768)
