Prophet Muhammad (peace be upon him) said:
There is a cure for everything in Surah Fatihah (baihaqi)
Some of the companions(may Allah be pleased with them) of the Prophet (peace be upon him) came across a tribe of Arab, and that tribe did not entertain them. While they were in that state, the chief of that tribe was bitten by a snake (or stung by a scorpion). The people of tribe said to the companions of the Prophet (peace be upon him) ), "Have you got any medicine with you or anybody who can treat with Ruqya?" The Prophet's (peace be upon him) companions said, "You refuse to entertain us, so we will not treat (your chief) unless you pay us for it." So they agreed to pay them a flock of sheep. One of the companion started reciting Surat-al-Fatihah and gathering his saliva and spitting it (at the snake-bite). The patient got cured and his people presented the sheep to them, but they said, "We will not take it unless we ask the Prophet (peace be upon him) (whether it is lawful)." When they asked Prophet Muhammad (peace be upon him), he smiled and said, "How do you know that Surat-al-Fatihah is a Ruqya? Take it (flock of sheep) and assign a share for me." (Al-Bukhari, 7:632)
