Musannaf Ibn Abi Shaybah

It is narrated from Hazrat Abu Dharr that the Noble Prophet (peace and blessings be upon him) said: For the one who eats, there is nourishment (that is, it also satisfies hunger).

Hazrat Ibn Abbas (may Allah be pleased with them both) says regarding the water of Zamzam that it is food for the eater (that is, it also satisfies hunger).

Hazrat Ibn Abbas (may Allah be pleased with both of them) said that we named it Shiba’ah, meaning “the one that satisfies hunger,” and we think that it is the best helper for the poor and those with dependents.

Hazrat Ka'b states that indeed it is in the Holy Qur'an that Zamzam water is one of the foods and is a source of healing for the sick.

Hazrat Qais bin Karkam narrates that I asked Hazrat Abdullah bin Abbas (may Allah be pleased with them both) to inform me about the water of Zamzam. He replied, "I will inform you with knowledge: Do not completely empty or finish its well, and do not speak ill of it. Surely, it is a food among foods and a cure for the sick."

It is narrated from Hazrat Jabir that the Holy Prophet (peace and blessings be upon him) said: Zamzam water is for whatever purpose it is drunk for (i.e., whatever intention you drink it with, that purpose will be fulfilled).
