Prophet SAWS (peace and blessings of Allaah be upon him) said, ‘The water of Zamzam is for whatever it is drunk for.’ (Muslim)
Zamzam water is the best and noblest of all waters, the highest in status, the dearest to people, the most precious and valuable to them. It was dug by Jibreel and is the water with which Allah quenched the thirst of Ismaa’eel. (Ibn Qayyim)
Zamzam is the name of a famous well in al-Masjid al-Haraam [the Sacred Mosque in Makkah], which is thirty-eight cubits away from the Ka’bah. It is the well of Ismaa’eel the son of Ibraaheem (peace and blessings of Allaah be upon them both), from which Allaah quenched the thirst of Ismaa’eel when he was an infant. His mother looked for water for him, but could not find any. She climbed to the top of al-Safaa, praying to Allaah to help her and give her water for Ismaa’eel, then she climbed to the top of al-Marwah and did the same. Allaah sent Jibreel, and he struck the earth with his heels, and water appeared.
It is sunnah to drink one’s fill of Zamzam water and to quench one’s thirst.
The fuqaha’ have mentioned the etiquette that is mustahabb (recommended) when drinking Zamzam water, such as facing the Ka’bah, saying Bismillah, pausing to take a breath three times, drinking one’s fill, praising Allaah after one finishes, and sitting whilst drinking it, as one should do when drinking other kinds of drinks. As regards the hadeeth of Ibn ‘Abbaas (may Allaah be pleased with him), who said, “I gave the Prophet (peace and blessings of Allaah be upon him) Zamzam water to drink whilst he was standing,” (reported by al-Bukhaari, 3/492), it is taken to mean that it is permissible to drink whilst standing, and the disapproval of doing so is understood to mean that it is makrooh.
The scholars also recommended that the person who drinks Zamzam water should sprinkle some of it on his head, face and chest, make lots of du’aa’ when drinking it, and to drink it for a purpose that will benefit him in this world or the next, because of the hadeeth in which the Prophet (peace and blessings of Allaah be upon him) said: “The water of Zamzam is for whatever purpose it is drunk for.” (Reported by Ibn Maajah, 2/1018; see Al-Maqaasid al-Hasanah by al-Sakhaawi, p. 359).
