At the wells of Badr, the Muslims and the Meccans met for battle. The Muslims were outnumbered by the Meccans 3 to 1. The battle began with an Arab tradition where each side sends out warriors to fight each other. Ali, the Prophet’s son-in-law and cousin, Hamza, the Prophet’s uncle, and Ubayda, a companion of the Prophet from his clan, represented the Muslims and defeated the Meccan warriors. The battle then began and ended with a decisive victory for the Muslims.
