"The water of Zamzam is good for whatever one intends"

Prophet (peace be upon him) said, 

"The water of Zamzam is good for whatever one intends (while drinking it).

Suwaid bin Saeed reported: "When the water of Zam-Zam was brought to Abdullah bin Al-Mobarak I saw that he drank a little, then turning his face towards the Ka'bah supplicated, 'O Allah! Ibn Abi Al-Mawali told us on the authority of Mohammad bin Al-Monkader, who narrated from Jaber that the Messenger of Allah (saws) said, "The water of Zam-Zam is good for whatever one intends (while drinking it)." I intend to drink this water to spare myself from going thirsty on the Day of Judgment.' Then he drank the rest of the water."
