The Prophet said: “The best water on the face of the earth is the water of Zamzam; it is a kind of food and a healing from sickness.”
One of the miracles of Zamzam water is its ability to satisfy both thirst and hunger. One of the Companions of the Prophet said that before Islam, the water was called “Shabba’ah” or satisfying. It was filling and helped them nourish their families.
After Islam, this powerful ability to quench thirst and fill stomachs remained.
