Yes, Zamzam water has a special physique that makes it advantageous water. This fact has been proved by a group of Pakistani researches. The Haj research center also conducted special researches about Zamzam water and it found that it has a wonderful physique that makes it different from other drinkable liquids. Mr. Sami Angaur the manager f the Haj research center told me that when they were digging for more wells of Zamzam they found the more they take from the well the more the amount of water becomes. They also examined the extent of its purity and they found that it is pure and sterile water that has no any germs in it. The prophet Mohammed [PBUH] said, “The water of Zamzam fulfils the purpose for which it has been drunk”. [Refer to Misnad Ahmed].
A man from Yemen was fond of reading Quran from a small Mushaf. As he becomes old he found that he couldn’t read Quran easily from that book because his sight is becoming weak. He heard about the water of Zamzam and its advantage of fulfilling the purpose for which it has been drunk. He came to Haj and he drank from Zamzam. He started reading from that small Mushaf of Quran easily and without any sight problems.
He achieved what he wanted because he was confident of that and has deep faith in the saying of the prophet [PBUH], “The water of Zamzam fulfils the purpose for which it has deep drunk” He was also confident and has deep belief in the Quranic sign in which Allah says, “When my servants ask thee concerning me, I am indeed close (to them): I listen to the prayer of every suppliant when he collect on me, let them also with a will listen to my call, and believe in Me. That may walk in the right way”. [2:186] Source: “You ask about the scientific miracles of Quran an Sunna and Shaikh Zindani answers” By Shaikh Abdel Majeed El Zindani.

Dr. Farooque Antar tells his own story. He says that he has been affected by a stone in his uriter and the doctor could nit remove or destroy it without a surgical operation. But he postponed the operation two times. Meanwhile he performed Omra and supplicated to Allah to cure him without undergoing operation. He drank from Zamzam water and prayed two Rakaat. Then he felt a benching in his uriter and hurried up to the toil and by the grace of Allah he saw the uniracle. The stone came out and he was cured without undergoing a surgical operation.
