124. When feeling some pain in the body

ضَعْ يَدَكَ عَلَى الَّذِي تَألَّمَ مِنْ جَسَدِكَ وَقُلْ: "بِسْمِ اللَّهِ" ثَلاَثاً، وَقُلْ سَبْعَ مَرَّاتٍ: "أَعُوذُ بِاللَّهِ وَقُدْرَتِهِ مِنْ شَرِّ مَا أَجِدُ وَأُحَاذِرُ"

Put your hand on the place where you feel pain and say: With the Name of Allah (three times). Then say seven times: I seek refuge in Allah and in His Power from the evil of what I find and of what I guard against.
