It is recommended to drink ZamZam water and pour it over head and body after offering Salah at the station of Ibrahim (AS). ZamZam water is available at both Masjid-ul-Haram and Masjid-e-Nabawi. While there is a pumping station at the ZamZam well in Haram, ZamZam is transported to Medina by water tankers. One of the extraordinary facts about ZamZam water is that the ZamZam well has provided continuous water supply for more than 4000 years which is a miracle in itself.
The history of ZamZam well goes back to the times of Prophet Ibrahim (AS). On Allah’s command, Ibrahim (AS) took his wife Hajira (RA) and son Ismail (AS) to Makkah, and left them there with only few dates and water. Once the provision ran out, Hajira (RA) and the child became thirsty. Hajira climbed up the Mount Safa to look for water and help. After seeing nothing she crossed the valley and climbed the Mount Marwa to do the same. When she found nothing here either, she started running between these hills in her anxiety. After she had done the circuits seven times, she heard a sound and returned to her child. She saw that an angel had stuck his wing on the ground and water was gushing forth from the spot, the same ZamZam spring that we see now. The name of the well came from the phrase ‘zomezome’ meaning stop flowing, a command repeated by Hajira (AS) while trying to contain the water.
Jabir (RA) reported that Prophet Muhammad (pbuh) said, “The Zam Zam water serves the purpose for which it is drunk”. Therefore, one should say, “I drink it with the intention that I may not get thirsty on the Day of Reckoning”.
ZamZam water is extremely pure and holds countless virtues which is one of the reasons why ZamZam is the best water on earth.
Abbas (RA) narrated that Prophet Muhammad (pbuh) said, “The difference between us and the Munafiqin (hypocrites) is that they do not drink to their fill”.
Therefore, whoever gets a chance to go on Hajj or Umrah should drink this holy water to their fill as long as one stays in the Holy City of Makkah. While drinking it he should pray profusely, and should also make the following Du’a:
Allahhumma inni as'aluka ilm-an na'fi-an wa rizqan wa'si-an wa shifa'am min kulli da'in
(O Allah! I request You earnestly to grant me useful knowledge, sustenance and provisions in abundance, good deeds, and cure from every disease).
