It is narrated from Ibn Abbas (may Allah be pleased with them both) that he said: "Hijr (i.e., Hatim) is a part of the House of Allah, and Allah Almighty has said: 'And let them circumambulate the Ancient House of Allah.' (__QUR_N__: Al-Hajj: 29) And the Messenger of Allah (ﷺ) performed Tawaf from behind the Hijr (Hatim)."
