Safa and Marwa (Arabic: ٱلصَّفَا وَٱلْمَرْوَة, romanized: Aṣ-Ṣafā wal-Marwah) are two small hills, connected to the larger Abu Qubais and Qaiqan mountains, respectively, in Mecca, Saudi Arabia, now made part of Al-Masjid al-Haram. Muslims travel back and forth between them seven times in what is known as saʿī (Arabic: سَعِي, lit. 'seeking/searching or walking') ritual pilgrimages of Ḥajj and Umrah.
Muslims run between the two mountains, which they believe was made a ritual as a tribute to Hajar's search of water for her child dying of thirst until she found a water source in the Zamzam Well. The space between the two mountains in which the pilgrims run is called al-Mas'aa.
