The well of Zam Zam water is located in Masjid Al-Haram in Mecca. This is purist form of water on the earth. People are taking water from this well from ages. There are so many benefits of Aab e zam zam.
Cure the Sick
Bibi Ayesha (R.A.) reported that she took Zam zam water home with her in bottles, and said, “The Messenger of Allah (peace and blessings of Allah be upon him) took some of it away with him, and he used to pour it on the sick and give it to them to drink.” (Reported by al-Tirmidhi, 4/37).
Differentiate Between Hypocrite and Believer
The difference between the believers and the hypocrites is drinking one’s fill of Zam zam water. (Narrated by Ibn Maajah)
When Bibi Hajra a.s made use of the small amount of food that Ibrahim a.s left for her and her baby, but ran out eventually and was soon thirsty and hungry-her milk dried up, her baby Ismail a.s became hungry and began to cry. Hajra a.s couldn’t afford seeing her son in pain so climbed up the hill which was later called As-Safa, to see if there was anyone in the horizon. She saw no one. She then climbed down, and reaching the valley, ran to the other hill, later called Al –Marwa, doing the same again, all this time her son twisting and turning in hunger. She repeated this seven times, and on the 7th time reached the top of the hill and heard a sound. To her amazement she found it coming from beneath the feet of Ismail a.s. At that point Jibra’eel a.s began digging the well of Zam-zam from beneath his feet. Hajra a.s was excited to contain the water, it being a desert and so arid and dry-the water would seep into the ground, and she tried making a pool to contain it.
