Question:
Is there an authentic hadith regarding the benefit of the water of Zamzam?

Answer:
The hadiths that are authentic indicate that the water of Zamzam is noble water and blessed water. It is established in the authentic collections that the Prophet (peace and blessings be upon him) said regarding Zamzam: And in a narration in Abu Dawud with a good chain, it was added: So this authentic hadith indicates its virtue, that it is food that satisfies hunger and a cure for sickness, and that it is blessed.
It is the Sunnah to drink from it, just as the Prophet (peace and blessings be upon him) drank from it, because of the blessing it contains. It is good food, blessed food, and food from which it is prescribed to take when it is available, as the Prophet (peace and blessings be upon him) did. This authentic hadith indicates what was mentioned before regarding its virtue, that it is blessed, that it is food that satisfies hunger and a cure for sickness, and that it is recommended for the believer to drink from it when it is available to him. It is permissible for him to perform ablution with it, and it is also permissible to use it for cleaning oneself after relieving oneself and for the full ritual bath for major ritual impurity if there is a need for that.
It is established from him (peace and blessings be upon him) that water gushed forth from between his fingers, and then the people took what they needed from this water to drink, to perform ablution, to wash their clothes, and to clean themselves. All of this took place. If the water of Zamzam is not like the water that gushed forth from between the fingers of the Prophet (peace and blessings be upon him), it is not above that; both are noble water. So if it is permissible to perform ablution, take a full ritual bath, clean oneself, and wash clothes with the water that gushed forth from between his fingers (peace and blessings be upon him), then it is likewise permissible with the water of Zamzam.
In any case, it is pure, good water, and it is recommended to drink from it. There is no blame in performing ablution with it, no blame in washing clothes with it, and no blame in using it to clean oneself if there is a need for that, as mentioned before. And praise be to Allah.
