438. The zam zam water spring. 

This verse of the Quran (3:97) says there are ‘clear proofs available in Makkah’. By clear proof it is meant, is devoid of any obscurities and doubtfulness, and can be witnessed by people, and withstand all scrutiny.

There may be much more evidence not yet witnessed by people, and may be discovered in the future. But the most significant evidence is the ZamZam spring.

 Prophet Ibrahim left behind his wife Hajr, and son Ismail in an isolated place at the behest of Almighty God. When Ismail as a child cried out for water it was Archangel Jibreel who created a water spring by striking the ground. This water spring is in existence even today and is known as the ZamZam well located in the place now known as Makkah.

This water spring now known as the Zam Zam well is the greatest wonder that stands testimony to the fact Islam is the true religion of God.

This well is 18 feet in width and 14 feet deep.

With an all-time water storage of 5 feet deep. 

Water is drawn from this well every second of the day, and people from all parts of the world gather there every day, and during the time of Haj and the month of Ramadan, nearly 3 million people gather there every day, and this well is the only source of supply of water for the entire floating as well as the permanent population.

The people from different countries of the world who gather carry with them a minimum of 30 liters each on their journey back home. .

And the water from the same well is being supplied to people who gather at the second most important masjid of the world at Madina. 

The fact that a well in a desert without any qualifying agent nearby in the form of a lake or a pond or a river or a canal can supply nearly 3 million people non-stop without getting dried up is the biggest wonder of all.

Any water spring for that matter gets dried up within a period of a few or many years, but this spring remaining alive for centuries together is again a wonder. 

Any water source is bound to be covered with algae and organisms that contaminate the water, and is the reason disinfectants like chlorine are added at the source. But water from the Zamzam well, right from the time it was sourced till today no disinfectants has been used and neither any safety measures utilized to protect it.

Water which is not protected by proper treatment normally becomes unfit for human consumption, but water from this source when tested in 1971 by a lab in Europe found it to be the most fit for human consumption.

And it was found to be quite different from water from other sources. The presence of calcium and magnesium were found to be more in this water than from other sources. These salts have a rejuvenation effect on humans, and people who drink it can experience the same. This water also contains fluoride that destroys germs.

This wonder known as the zamzam water spring, need not be considered and equated with other wonders of the world. 

The other wonders have not been subjected to scrutiny and are blind beliefs. But it is practically seen that the water from this spring is being supplied for the past thousands of years continuously, after undergoing various tests, hence this remains as a true wonder, without a parallel.
