من قسّم أرض الحجاز؟
As the land of Mecca and Medina, the Hijaz was where Muhammad was born, and where he founded a Monotheistic "Ummah" (Community) of followers, bore patience with his foes or struggled against them, migrated from one place to another, preached or implemented his beliefs, lived and died. Given that he had both followers and enemies here, a number of battles or expeditions were carried out in this area, like those of "al-Aḥzāb" ("the Confederates"), Badr and Ḥunayn. They involved both Meccan companions, such as Hamzah ibn Abdul-Muttalib, Ubaydah ibn al-Harith and Sa`d ibn Abi Waqqas, and Medinan companions. The Hijaz fell under Muhammad's influence as he emerged victorious over his opponents, and was thus a part of his empire.
