إِنَّ الصَّفَا وَالْمَرْوَةَ مِنْ شَعَائِرِ اللَّهِ ۖ أَبْدَأُ بِمَا بَدَأَ اللَّهُ بِهِ
Innas-Safa wal-Marwata min sha'a'irillah. Abda'u bima bada'Allahu bih
Indeed, Safa and Marwa are among the symbols of Allah. I begin with what Allah began with.
This is said at the beginning of Sa'i, before ascending Mount Safa. The ritual of walking between Safa and Marwa commemorates Hajar (AS) — the mother of Isma'il — running between these two hills searching for water for her infant son, until the well of Zamzam miraculously sprang forth.
