paragraph_text: Arbitration agreement
  
  Mu'awiya now proposed that representatives from both sides should find a Quranic resolution. Mu'awiya was represented by his ally Amr, whereas, despite Ali's opposition, the majority in his camp pressed for the neutral Abu Musa, the erstwhile governor of Kufa. The arbitration agreement was written and signed on 2 August 657, stipulating that the two representatives should meet on neutral territory, adhere to the Quran and Sunna, and restore peace. Both armies left the battlefield after the agreement. The arbitration agreement thus divided Ali's camp, as many did not support his negotiations with Mu'awiya, whose claims they considered fraudulent. By contrast, the agreement strengthened Mu'awiya's position, who was now an equal contender for the caliphate.
