Zamzam

Zamzam: زَمزَم The sacred well inside the Haram (the grand mosque) at Makkah. Prophet Ibrahim was commanded by Allah to leave his wife, Hajra, and his infant son, Ismail, in the then barren valley of Makkah.
Hajra, travelled between the two hills As-Safa and Al-Marwa seven times looking for water. When she returned to Ismail, she found him crying and water gushing at his feet. This water was thus named the well of Zamzam.
