          when he reached Roha, he realized his mistake, and made plans
        
        
          to turn once again on the Muslims’ stronghold. But even at this
        
        
          time of utter disarray, the Prophet’s information system was still
        
        
          working very effectively. He heard about Abu Sufyan’s intention
        
        
          and decided to go out to meet him. Immediately he reassembled
        
        
          his shaken army and set off towards Makkah. Contrary to his
        
        
          normal practice, which was to maintain a veil of the utmost secrecy
        
        
          over military manoeuvres, this expedition was given a fanfare of
        
        
          publicity. When the Muslims reached Hamra al-Asad, eight miles
        
        
          from Madinah, Abu Sufyan heard of the pursuit. Thinking that
        
        
          fresh reinforcements must have arrived, he gave up his idea of
        
        
          attacking Madinah and returned to Makkah. The Prophet turned
        
        
          back to Madinah once he was sure of the withdrawal of Abu
        
        
          Sufyan’s army.
        
        
          One year after the Battle of Mutah, which occurred in the
        
        
          month of Jumada al-Awwal, 8
        
        
          a
        
        
          .
        
        
          h
        
        
          ., the Byzantine emperor started
        
        
          gathering his forces on the Syrian border. The Ghassanids, along
        
        
          with other Roman allies among Arab tribes in the region, followed
        
        
          the emperor’s lead. In response, the Prophet advanced to Tabuk
        
        
          with an army of 30,000. The expedition to Tabuk was really a
        
        
          military pre-emptive strike designed to awe the enemy, so that
        
        
          they would lose heart and abandon their hostile intentions.When
        
        
          the Prophet reached Tabuk, he heard that Caesar was no longer
        
        
          advancing to meet the Muslims but, instead, was beginning to
        
        
          withdraw his forces from the frontier. There was now no question
        
        
          of a battle, and Caesar’s very withdrawal had assured the Prophet
        
        
          of a moral victory, which he decided to turn to his own political
        
        
          advantage. During his 20-day stay inTabuk, he established contact
        
        
          with the neighbouring Arab tribes, who were at that time under
        
        
          Roman influence. The Christian chieftain of Daumat al-Jandal,
        
        
          Ukaidir ibn Abdul Malik Kindi, Yohanna ibn Ruya from Ayla,
        
        
          along with Christians of Maqna, Jarba and Azruh, agreed to pay
        
        
          
            jizya
          
        
        
          , a tax paid by non-Muslim states as a sign of submission to the
        
        
          Muslim rule, and to buy protection and freedom to practice their
        
        
          religion and culture.
