زمزم
According to Islamic tradition, Ibrahim rebuilt the "Baitullah" ("House of God") near the site of the well, a building which had been originally constructed by Adam (Adem), and today is called the Kaaba, a building toward which Muslims around the world face in prayer, five times each day. The Zamzam Well is located approximately east of the Kaaba. In other Islamic tradition, Muhammad's heart was extracted from his body, washed with the water of Zamzam, and then was restored in its original position, after which it was filled with faith and wisdom.
