Narrated Sa'id Ibn Zaid: The Prophet ﷺ said, "Al-Kam'a is like the Mann (sweet resin or gum) (in that it grows naturally without human care) and its water is a cure for the eye diseases".
The Prophet Muhammad ﷺ was known for his wisdom and knowledge in many areas including medicine and health care. He taught his followers to use natural remedies such as honey, olive oil, dates etc., whenever possible before resorting to modern medicines or treatments which may have side effects or other risks associated with them. This hadith serves as an example of this wisdom by encouraging us to look towards nature for cures instead of relying solely on modern medicine when treating illnesses or ailments such as eye diseases.
