ZamZam water level is around 10.6 feet below the surface. It is the miracle of Allah that when Zam Zam was pumped continuously for more than 24 hours with a pumping rate of 8,000 liters per second, water level dropped to almost 44 feet below the surface,
BUT WHEN THE PUMPING WAS STOPPED, the level immediately elevated again to 13 feet after 11 minutes. 8,000 liters per second means that 8,000 x 60 = 480,000 liters per minute 480,000 liters per minutes means that 480,000 x 60 = 28.8 Million liters per hour And 28.8 Million liters per hour means that 28,800,000 x 24 = 691.2 Million liters per day So they pumped 690 Millions liters of zamZam in 24 hours, but it was re-supplied in 11 minutes only.
There are 2 miracles here, the first that ZamZam was re filled immediately, & the second is that Allah Holds the extra-ordinarily powerful Aquifer for not throwing extra ZamZam out of the well, otherwise the world will SINK.
It is the translation of the word ZamZam, which means Stop! Stop!! said by Hajirah Alaih As Salaam.
Zamzam water has no colour or smell, but it has a distinct taste.
