Safa and Marwa are two small hills within Masjid al-Haram associated with the story of Hajar and her search for water for her son Ismail. Pilgrims walk between them seven times in the Sa'i ritual during Hajj and Umrah. The corridor is approximately 450 meters long, air-conditioned, and equipped with separate paths for pedestrians and wheelchairs. The ritual commemorates Hajar's desperate search that led to the miraculous emergence of the Zamzam Well. The hills are now enclosed within the mosque complex with multiple floors to accommodate large crowds.
