Muhammad bin Ishaq narrated: Then the people pressed on until, when they reached the borders of al-Balqa', the armies of Heraclius met them. The Muslims withdrew to a village called Mu'tah, and there the two armies clashed. The Muslims arranged their ranks, appointing over their right wing a man from Banu Udhrah called Qutbah bin Qatadah, and over their left wing a man from the Ansar called Abayah bin Malik. Then the fighting broke out, and Zayd bin Harithah (may Allah be pleased with him) fought holding the banner of the Messenger of Allah (peace and blessings be upon him) until he was martyred among the spears of the enemy.
