Back in despair to Ishmael, she saw the baby scratching the ground with his leg and a water fountain underneath.[2][3] Because of the presence of water, tribes started to settle in Mecca, Jurhum being the first such tribe to arrive. When grown up, Ishmael married in the tribe and started living with them.[3] The Quran states that Ibrahim, along with his son Ishmael, raised the foundations of a house that is identified by most commentators as the Kaaba. After the placing of the Black Stone in the Eastern corner of the Kaaba, Ibrahim received a revelation in which Allah told the aged prophet that he should now go and proclaim the pilgrimage to mankind.[2] The Quran refers to these incidents in 2:124-127 and 22:27-30.
