Musannaf Ibn Abi Shayba 28:622

Waki’ narrated to us, he said: Salih bin Abi al-Akhdar narrated to us, from al-Zuhri, from ‘Urwah, from Usamah, who said: The Messenger of Allah (may Allah bless him and grant him peace) sent me to a land called Abna. He said: "Go to it in the morning, then burn [it]."
