Peace, mercy, and blessings of God be upon you. The Messenger of God, may God's prayers and peace be upon him, said: "The truffle is from the Mann, and its water is a cure for the eye." This hadith was narrated by Al-Bukhari and Muslim from Saeed bin Zaid, may God be pleased with him. The truffle (or faqa' as it is called in some regions) is a fungus that grows underground and does not require cultivation or watering. The water of the truffle is used as medicine for the eye, especially in cases of conjunctivitis or cataracts. Ancient experiments have proven that truffle water is beneficial for the eye.
