Yazid bin Abu Ubaid says that once I saw a scar from a wound on the shin of Sayyiduna Salamah bin Akwa’. I asked him,“O Abu Muslim! What is this scar?”He replied,“I received this wound during the Battle of Khaybar. When I was struck, people said, ‘Salamah is finished.’ But then I was brought to the Prophet ( صلی اللہ علیہ وسلم ), and the Prophet ( صلی اللہ علیہ وسلم ) blew on it three times, and since then I have never felt any pain from it again.”
