when bitten by a scorpion:

Prophet Mohammad's (SAW) action when bitten by a scorpion:

Once a scorpion bit Prophet Mohammad (SAW.) while he was in Salaat. On completion of the Salaat he said: "Curse be on the scorpion as it does not leave the person performing Salaat nor anyone else". He then asked for water and salt and dissolved that salt in the water. He rubbed the solution on the wound and kept reciting Surah-al-Kaafiroon, Falaq and Naas. (Hisnul Hasin from Tabarani in Al-Sagheer)
