Battle of al-Musayyakh (12 AH)

When the people of Husayd and al-Khanafis had been routed, Khalid ibn al-Walid (may God be pleased with him) arranged with his commanders al-Qa'qa', Abu Layla, A'bad and 'Urwa a single night and hour. They gathered at al-Musayyakh of the Banu al-Barsha' and raided the camp of al-Hudhayl ibn 'Imran while its men slept, attacking from three directions and killing them. Among the strangest episodes was the killing of Abd al-Uzza ibn Abi Rahm and Labid ibn Jarir, who had both embraced Islam and carried a document from Abu Bakr confirming their conversion. When this reached Abu Bakr, he paid their blood-money and entrusted their children to care; Umar counted their killing against Khalid. Harqus ibn al-Nu'man had advised them, but they did not accept. He told his family, "Drink the drink of one bidding farewell," and drank until his head was struck, and it fell into the bowl of wine. ¹.
