[Machine] He killed Suwaid bin As-Samit in the pre-Islamic era. When the Messenger of Allah ﷺ arrived in Medina, Harith bin Suwaid bin As-Samit and Mujdhir bin Ziyad embraced Islam and witnessed the Battle of Badr. Harith sought to kill Mujdhir in revenge for his father but he was unable to do so that day. On the day of Uhud, when the Muslims went on an expedition, Harith came from behind Mujdhir and struck him in the neck, killing him. The Messenger of Allah ﷺ then returned to Medina and later went to Hamra' al-Asad. When he returned, Jibreel (Gabriel) came to him and informed him that Harith bin Suwaid had killed Mujdhir bin Ziyad out of vengeance. The Prophet ﷺ ordered his companions to execute Harith by striking him with a sword, and he was killed. Harith pleaded to speak to the Messenger of Allah ﷺ , but Awaim refused him. Harith then grabbed Awaim, wanting to speak to the Messenger of Allah ﷺ , but the Prophet ﷺ intended to mount his riding animal. Harith said, "By Allah, O Messenger of Allah, I killed him. By Allah, I did not kill him out of turning back from Islam or doubting it, but it was Satan's incitement, and I was given authority over my own self. Verily, I turn to Allah in repentance and to the Messenger of Allah, I will pay his blood money, fast for two consecutive months, free a slave, and feed sixty poor people. Verily, I turn to Allah in repentance." The Prophet ﷺ held the reins of his riding animal, and the sons of Mujdhir were present, and the Messenger of Allah ﷺ did not speak to them until he fully absorbed the words of Harith. Then he said, "Bring him forward, O Awaim, and strike his neck." And his neck was struck.
