Performing the "Sa'ee" serves to commemorate Hajar's search for water for her son and God's mercy in answering prayers. Two walkways guide pilgrimes from Safa to Marwa, and from Marwa to Safa, with two narrower walkways in the center to serve elderly and disabled pilgrims. The walkways between the two mountains are collectively called the "Mas'aa" () and are air-conditioned. Water pumped from the Zamzam Well is also available on the way. "Sa'ee" is an integral part and "rukn" of Hajj and Umrah.
