Hadith 2202

Uthman b. Abu al-'As Al-Thaqafi reported that he made a complaint of pain to Allah's Messenger (may peace be upon him) that he felt in his body at the time he had become Muslim. Thereupon Allah's Messenger (may peace be upon him) said: Place your hand at the place where you feel pain in your body and say Bismillah (in the name of Allah) three times and seven times A'udhu billahi wa qudratihi min sharri ma ajidu wa uhadhiru (I seek refuge with Allah and with His Power from the evil that I find and that I fear).

حَدَّثَنِي أَبُو الطَّاهِرِ، وَحَرْمَلَةُ بْنُ يَحْيَى، قَالاَ أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، أَخْبَرَنِي نَافِعُ بْنُ جُبَيْرِ بْنِ مُطْعِمٍ، عَنْ عُثْمَانَ بْنِ أَبِي الْعَاصِ الثَّقَفِيِّ، أَنَّهُ شَكَا إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَجَعًا يَجِدُهُ فِي جَسَدِهِ مُنْذُ أَسْلَمَ ‏.‏ فَقَالَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ ضَعْ يَدَكَ عَلَى الَّذِي تَأَلَّمَ مِنْ جَسَدِكَ وَقُلْ بِاسْمِ اللَّهِ ‏.‏ ثَلاَثًا ‏.‏ وَقُلْ سَبْعَ مَرَّاتٍ أَعُوذُ بِاللَّهِ وَقُدْرَتِهِ مِنْ شَرِّ مَا أَجِدُ وَأُحَاذِرُ ‏"‏ ‏.‏
