If he was committed to that he will stay protected till the day when Allah takes his soul."

Al-Qummi states in his Tafseer Book: Baker bin Mohammad reported from Imam Abou Abdellah (Pbuh) that he said: "The cause of the descent of the two refuge chapters (Al-Falaq and Al-Nass) is that the Messenger of Allah (Pbuhp) was sick and so Jibraeel descended carrying these two chapters with him and recited them for him to refuge him."
Al-Qotb Al-Rawandy states in Al-Da'awat Book: Ameer Elmo'mineen (Pbuh) said: "The Messenger of Allah (Pbuhp) was bit by a scorpion so he called for water.

Then he called for salt and dissolved it in the water and then poured the water on the bite so that it heals."
The two sons of Bistam state in Tob Al-A'imma Book: Ismaeel bin Abi Ziad reported from Imam Sadiq (Pbuh) that he said: "When the body of the Messenger of Allah (Pbuhp) used to become weak or when he used to suffer from headache he used to open his hands, recite Al-Fatiha and the two refuge chapters then wipe his hands over his face. Thus he was relieved from everything he was suffering."
