Zamzam : The Miracle from Allah
Well, or
just Zamzam; Arabic: �) is a
well located within the Masjid al Haram
in Mecca, 20 meters east of the Kaaba,[1] the holiest
place in Islam. According to Islamic tradition it was a miraculously- generated
source of water from angel Jibril (Gabriel), which
began thousands of years ago when Ibraham's infant
son was thirsty. Millions of pilgrims visit the well each year while performing
the Hajj or Umrah pilgrimages, in order to drink its
water. By Saudi law, the water cannot be sold outside of the kingdom, but
because of strong demand there is a thriving market in fake Zamzam
water in other countries.
Zam Zam is 18X14 ft & 18 meter deep water well.
It started
4000 yrs ago. 
Never dried since then.
Never changed the taste, no Algea or plant
growth in the pond, thus no disease caused.
It was
tested by European Laboratories & declared fit for drinking.
This small
pond provides water to millions of people through heavy motors pulling 8000lit:
per second and after 24 hours in only 11 mins
completes its level. Thus its water level never decreases
SUBHANALLAH
