Yazid b. Abu `Ubaid said:
I saw the mark of a blow on the leg of Salama b. al-Akwa' and asked, "What is this blow, Abu Muslim?" He replied, "It is a blow I received at the battle for Khaibar which made the people say I had been killed. I went to the Prophet who blew spittle on it three times, and up to now I have been having no trouble with it."
Bukhari transmitted it.
