It is narrated from Sayyiduna Uthman bin Abi al-As (may Allah be pleased with him) that he came to the Messenger of Allah (peace and blessings be upon him), and he had such pain that he was near to perishing from it. The Prophet (peace and blessings be upon him) said: "Place your right hand on the place of pain and pass it over seven times, and say «أَعُوذُ بِعِزَّةِ اللّٰهِ وَقُدْرَتِهِ، مِنْ شَرِّ مَا أَجِدُ»." Sayyiduna Uthman bin Abi al-As (may Allah be pleased with him) says: I did exactly that, and Allah removed my pain. After that, I always instructed my family and other people to do the same.
