Invasion of Buhran
Throughout the invasion, they did not meet any enemies, and no fighting took place. Muhammad occupied the area for three months. The expedition is regarded as a "patrolling invasion", according to Muslim scholar Saifur Rahman al-Mubarakpuri.
This event is mentioned in Ibn Hisham's biography of Muhammad, and other historical sources. Modern secondary sources which mention this include the award-winning book  Ar-Raheeq Al-Makhtum (The Sealed Nectar).
After this raid, Muhammad also accepted ransom for some of the prisoners he captured in Badr.
