Amr bin Umayyah al-Damri

Amr bin Umayyah al-Damri is a companion of the Islamic Prophet Muhammad. Amr bin Umayyah al-Damri was sent to assassinate Abu Sufyan

He participated in the The Mission of Amr bin Umayyah al-Damri in the year 627. Amr bin Umayyah al-Damri was sent to assassinate Abu Sufyan to avenge Khubyab bin Adi. According to the Muslim scholar Safiur Rahman Mubarakpuri, the Quraysh ordered Khubyab bin Adi to be crucified by Uqba bin al-Harith during the Expedition of Al Raji because he had killed Uqba bin al-Harith's father. 3 polytheists were killed by Muslims and 1 was captured

He was also one sent the investigate the events of the Expedition of Bir Maona. When the news of this massacre reached Muhammad, he was greatly grieved and sent Amr bin Umayyah al-Damri and an Ansar to investigate the whole matter. On his way back to Qarqara, Amr bin Umayyah rested in the shade of a tree, and there two men of Banu Kilab joined him. When they slept, Amr killed them both, thinking that by doing that he would avenge some of his killed companions.

Then he found out that they had been given a pledge of protection by Muhammad. He told Muhammad what he had done. Then Muhammad said to ‘Amr, that he (Muhammad) must pay a debt for the killing of those he pledged protection to (the Dhimmi's)

He was sent as an envoy to the king of Ethiopia (then Abyssinia) called Aṣḥama ibn Abjar to invite him to Islam
