One of the customs of the pilgrimage is to cross the space between the two small hills Safa and Marwah near the Ka'ba seven times, within the imposing Masjid al-Haram mosque. The corridor traversed by the pilgrims is now 450 metres long. The walk in question is a way of remembering Hajar's journey to fetch water for her son. A few kilometres from the centre of Mecca, the Mountain of Light (Jabal al-Nour), where Mohammed is said to have had his first revelation with God, is also a respected and visited place.
