Zam Zam means "Stop Stop". It is a well in masjid Al Haram some 20 meters away from Kaaba. Normally a well is dried up after 70 years in that Saudi soil but zam zam is giving water since last 5000 years.
It is the purest, holyiest and healthiest water having odourless and colourless qualities. Our prophet Muhammad PBUH said:-
"In it there is food for the hungry and a cure for the ill” (Al-Tabrani, 1994: No. 11004).Muh. 9, 1445 AH.
Histirically, Prophet Ibrahim had left his son Ismaeel and his wife Hajar in an "uncultivated valley" presently Makkah by Allah's will. When their food was finished the mother Hajar started running back and forth between Safa and Marwa for 7 times.
At this point this water source streamed up under the foots of Hazrat Ismaeel by the will of Allah to quench his and his mother's thurst.
Prophet Muhammed (peace be upon him) said: “May Allah bestow mercy on Ismail’s mother! Had she left the Zamzam flow without trying to control it, Zamzam would have been a stream flowing on the surface of the earth.”
Please note that before our Prophet Muhammad’s grandfather, Abdul Muttalib, and many years after him, the flow of Zamzam water abated and later completely blocked. Abdul Muttalib received a vision in sleep to re-dig the well, and so he located the well and dug it for it to start pumping again and feed the pilgrims. This became the process carried out by Abdul Muttalib’s family and his son Abbas Bin Abdul Muttalib inherited this responsibility after him.
Currently this well is 30 meters deep and its pump is sucking water with a high speed of 11 liters per second but water is still coming.
