The place named after (Al-Haswa) in the Noble Prophet’s Mosque is located behind the honorable Rawda and is an extension of the mosque. Haswa means the unroofed land, it was built in the era of the Messenger (may Allah bless him and grant him peace), and it was a place where the Companions gathered (may Allah be pleased with them) to talk about their concerns. In the Prophet’s era, the pebble was the seat of the brigades and a hospital for the treatment of the sick and the wounded, and it was covered with dust, so if the Companions (may Allah be pleased with them) used to rise from their prostration, they wiped their faces from the traces of dust, so Omar Ibn Al-Khattab (may Allah be pleased with him) ordered to bring pebbles from the Aqeeq Valley, The land was spread with it, and it was called "Al-Batiha".
