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. 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. According to the Muslim collection of Hadith, Abu Dharr Ghifari, a Companion, noted that when he first arrived in Makkah during the early days of Islam, he survived only on Zamzam water for a whole month. Not only did he satisfy his hunger and thirst, he became obese. More recently, in the last few decades, scientists have collected samples of Zamzam water and they have found certain peculiarities that make the water healthier, like a higher level of calcium. Apart from its ability to serve as satisfying food and drink, Zamzam water's health benefits are also commended. The Prophet said it was a healing from sickness. This is why pilgrims to Makkah to this day collect it in bottles to bring for relatives and friends back home who are ill. The Prophet used to carry Zamzam water in pitchers and water skins back to Madinah. He used to sprinkle it over the sick and make them drink it.
