There is very scarce information regarding women in pre-Islamic Arabia. Most of it originates from Hadith and historical traditions, pre-Islamic poetry, and early biographical accounts, or from conclusions from Qur'anic statements. According to Islamic history sources, the first wife of Muhammad, Khadija, was a prosperous business woman who proposed to Muhammad (as opposed to being proposed to). They additionally say the wife of his chief-rival, Abu Sufyan (Hind), was politically active and was present at the Battle of Badr including conflicting accounts of her personally defiling the body of one of Muhammad's uncles. Legal status and treatment Tribe Many assumptions have been made about pre-Islamic law due to discrepancies in the understanding of how law was enacted within the Arabian society.

During the pre-Islamic times between 3500 and 3000 BCE, many of the city-states containing the individual tribes continually changed who had the authority to dictate. Much of this change occurred due to the tribal warfare taking place among these tribes. As the governmental power continued to be overturned and replaced, the laws towards women became more limiting as time went on. For some time, husbands had the right to pawn their wives and children, beat them mercilessly, or pull their hair without being penalized for these actions. The only chief right a woman had during these times was stated in the Code of Hammurabi in 1752 BCE, "women could obtain a divorce only with great difficulty. If a woman so hated her husband, that she has declared, 'you may not have me', her
