Ishmael and Hagar being taken to Mecca by Abraham in Islamic texts is an important part in the story of Ishmael, as it brings the focus to Mecca and is the beginning of Mecca's sanctification as a holy area.: Islamic tradition says Abraham was ordered by God to take Hagar and Ishmael to Mecca, and later Abraham returned to Mecca to build the Kaaba. In many of these accounts, the Sakina (something like a wind or spirit sent by God), or the angel Gabriel (Jibral) guides them to the location of the Kaaba, at which point Abraham builds it and afterwards, leaves the other two there (other versions discussed below say the construction of the Kaaba occurred later and that Ishmael took part in it). Generally, it is said that Hagar asks Abraham who he is entrusting herself and Ishmael to as he leaves them. He answers that he is entrusting them to God, to which Hagar then makes a reply that shows her faith, stating that she believes God will guide them. Hagar and Ishmael then run out of water and Ishmael becomes extremely thirsty. Hagar is distressed and searches for water, running back and forth seven times between the hills of Al-Safa and Al-Marwah. Hagar is later remembered by Muslims for this act during the Hajj, or pilgrimage, in which Muslims run between these same hills as part of the Sa'yee. When she returns to Ishmael, she finds either him or an angel scratching the ground with their heel or finger, whereupon water begins flowing and Hagar collects some or dams it up. This spring or well is known as Zamzam. At some point, a passing tribe known as the Jurhum sees birds circling the water and investigates. They ask Hagar if they can settle there, which she allows, and many versions say as Ishmael grew up he learned various things from the tribe. There are numerous versions of this story, each differing in various ways. The versions used in this summary, as well as others, can be found in al-Tabari's history and are recounted in Reuven Firestone's Journeys in Holy Lands.
