Amal for a scorpion bite

Sayyidna Ali (Radiyallahu Anhu) reports that once a scorpion bit the messenger of Allah (Sallallahu Alaihi Wasallam), so he asked for water and salt. He began applying the water on the spot where the scorpion bit him, whilst reciting Surah Al- Kafirun, Surah Al-Falaq and Surah An-Nas. [Tafseer e Mazhari]
