The battle of al-Nahrawan was Ali ibn Abi Talib's fight against the Kharijites who rebelled against him after the arbitration. al-Tabari mentions "the report of the day of al-Nahr" within the accounts of 37 and 38 AH. ¹

al-Suyuti relates that the Kharijites came out after the arbitration, saying "No judgement but God's," and camped at Harura. Ali sent Ibn Abbas to them, who debated with them, and many of them returned. A group remained, moved to al-Nahrawan and blocked the road. Ali marched against them and killed them, and among those killed was Dhu al-Thudayya, in 38 AH. ²

al-Mas'udi relates that the Kharijites gathered four thousand men and gave their allegiance to Abd Allah ibn Wahb al-Rasibi, and that they slaughtered Abd Allah ibn Khabbab. Ali marched against them with thirty-five thousand men, and ten thousand from Basra with him. ³
