Her son Ishmael was dying of thirst. She ran between the hills of al-Safa and al-Marwah, back and forth. On the seventh run, Ishmael stomped on the ground, and a spring appeared. This is the Zamzam Well, a few metres from the Kaaba in Mecca.
When Muslims perform pilgrimage, they also run seven times between the hills in memory of Hagar’s courage, motherhood, leadership.
