Sunan Abi Dawud

Yazid b. Abi ‘Ubaid said :I saw a sign of injury in the shin of Salamah. I asked : What is this ? He replied : I was afflicted. I was afflicted by it on the day of Khaibar. The people said : Salamah has been afflicted. I was then brought to the Prophet (ﷺ). He blew on me three times. I did not feel any pain up till now
