Musannaf Ibn Abi Shayba 34:304

Ya'qub ibn Ishaq ibn Hajar narrated to us, Abu Musa narrated to us, Damra narrated to us, from Yazid ibn Abi Yazid, from a man he named, who said: The first to tie a banner (liwa') was Ibrahim, the Friend of the Most Merciful. It reached him that a people had raided Lot and taken him captive, so he tied a banner and marched toward them with his slaves and his freedmen until he overtook them and rescued him and his family.
