What is Sa' y?

The sa'y (or saee) is the going back and forth between the two hills of As-Safaa and Al-Marwaa in Mecca by the Kaaba.

This is done in rememberence of Hagar, the mother of Ishmael, who ran back and forth looking for any source of food or water for her child.

It is done during the personal visit to the Kaaba (Umraa) as well as the major pilgrimmage (Hajj)
