What to say and do when feeling some pain in the body

بِسْمِ اللهِ (ثَلاثاً) أَعُوذُ باللهِ وَقُدْرَتِهِ مَنْ شَرِّ مَا أَجِدُ وَأُحَاذِرُ. (سبع مرات)

Place your hand at the site of the pain and say: In the name of Allah (3 times). Then supplicate seven times: I take refuge in Allah and within His omnipotence from the evil that I feel and am wary of. (7 times)
