Uthman b. Abu al-As Al-Thaqafi reported that he made a complaint of pain to Allah's Messenger (saw) that he felt in his body at the time he had become Muslim. Thereupon Allah's Messenger (saw) said, Place your hand at the place where you feel pain in your body and say Bismillah 3 times and 7 times I seek refuge with Allah and with His Power from the evil that I find and that I fear.
