Nafi' bin Jubair narrates about Sayyiduna 'Uthman bin Abu al-'As Thaqafi (may Allah be pleased with him): He complained to the Prophet Muhammad (peace be upon him) about a pain (i.e., illness) that had afflicted him after accepting Islam. The Prophet (peace be upon him) said to him: "Place your hand on the spot where you feel pain in your body and recite 'Bismillah' three times, and then say: 'I seek refuge in Allah and His power from the evil of what I find and what I fear.' Recite this seven times."
