In Islam, the ritual walk between Safa and Marwa is called sa'i. Pilgrims perform it by traveling between the two hills seven times during hajj or umrah.
The rite commemorates Hagar's search for water for her son Ishmael, according to Islamic tradition. The hills are now enclosed within Masjid al-Haram in Mecca, and pilgrims walk through a long gallery connecting them.
Sa'i is different from tawaf, which consists of circling the Kaaba. It is also different from wuquf, the standing rite at Arafat, and ramy, the symbolic stoning performed at Mina. These distinct rites are all associated with pilgrimage but have different locations and meanings.
