Yahya related to me from Malik from Ibn Shihab from Urwa ibn az-Zubayr from A'isha that the Messenger of Allah, may Allah bless himand grant him peace, when he had a complaint, would recite the lastthree suras of Qur'an, over himself and blow. She said, "When his painwas great, I would recite it over him and wipe him with his right handhoping for its blessing."
