The exist of the world, universe human being, the birth of child from an embryo, the animals, the plants, the sky, the cloud, the sun, the moon, the stars, the planets, the air the water, the oceans and many many more are all the prove of existence of Allah and the miracle of Islam. The miracle of science is itself the miracle of Islam. One from the many greatest miracles of Islam which is a most wonderful is the Zamzan water. It is a well which was produce in Makkah by the Hazrat Ismail (PBUH) when he was left alone in a desert of Makkah without water with her mother Hajra., She searched for water in the hills of Safa and Marwa to give to her newly born son Hazrat Ismail (PBUH) As she ran from one place to another in search of water, her child rubbed his feet against the sand. A pool of water surfaced, and by the grace of God, shaped itself into a well which came to be called Zumzum water. This well has never dried up and it has always fulfilled the demand for water. It has always maintained the same salt composition and taste ever since it came into existence. It is equally popular all over the world as pilgrims visit Kaaba every year for Hajj and umrah they have always enjoyed the water that refreshes them even after when they went back to their home and give it as a gift to their relative. Zumzum water's appeal has always been universal. This water has never been chemically treated or chlorinated. Biological growth and vegetation usually takes place in most wells. This makes the water unpalatable owing to the growth of algae causing taste and odour problems. But in the case of the Zumzum water well, there wasn't any sign of biological growth.
