The Battle of Ajnadayn (Arabic: معركة أجنادين) was fought in July or August 634 (Jumada I or II, 13 AH),[2] in a location close to Beit Guvrin in the Roman-era Palestine region (present-day Israel); it was the first major pitched battle between the Byzantine (Roman) Empire and the army of the Arab Rashidun Caliphate. The result of the battle was a decisive Muslim victory. The details of this battle are mostly known through Muslim sources, such as the ninth-century historian al-Waqidi.
