Aḥmad ibn Yaḥyá al-Balādhurī, The Origins of the Islamic State (1916)
“ Those who lost an eye or suffered martyrdom. Abu-Sufyân ibn-Ḥarb was one-eyed. He had lost his eye in the battle of aṭ-Ṭâʾif. In the battle of al-Yarmûk, however, al-Ashʿath ibn-Ḳais, Hâshim ibn-ʿUtbah ibn-abi-Waḳḳâṣ az-Zuhri (i. e. al-Mirḳâl) and Ḳais ibn-Makshûḥ, each lost an eye. In this battle ʿÂmir ibn-abi-Waḳḳâṣ az-Zuhri fell a martyr. It is this ʿÂmir who once carried the letter of ʿUmar ibn-al-Khaṭṭâb assigning abu-ʿUbaidah to the governorship of Syria. Others say he was a victim of the plague; still others report that he suffered martyrdom in the battle of Ajnâdîn ”
