Mu'awiya ibn al-Mughira
Muʿāwiya ibn al-Mughīra ibn Abī al-ʿĀs ibn Umayya (Arabic: معاوية بن المغيرة بن أبي العاص بن أمية) was a member of the Banu Umayya alleged to be a spy against the Muslims during the time of the Islamic prophet Muhammad. He was captured during the Invasion of Hamra al-Asad, where Muhammad accused him of being a Meccan spy, he was the cousin of Uthman ibn Affan, had been captured after Uhud. Uthman gave him shelter. He was given a grace period of three days and arranged a camel and provisions for his return journey to Mecca. Uthman departed with Muhammad for Hamra-al-Asad, and Muawiya overstayed his grace. Though he fled by the time the army returned, Muhammad ordered his pursuit and execution. The orders were carried out.[1][2][3][4][5]
This incident is also mentioned in Ibn Ishaq and Ibn Hisham's biography of Muhammad.[6]
