I had a pain which was about to destroy me. So the Prophet ﷺ said : Wipe it with your right hand seven times and say : “I seek refuge in the dominance of Allah, and His might from the evil of what I find.” Then I did it. Allah removed (the pain) that I had, and I kept on suggesting it to my family and to others. (Using translation from Abū Dāʾūd 3891)
أَخْبَرَهُ أَنَّ عُثْمَانَ بْنَ أَبِي الْعَاصِ أَتَى رَسُولَ اللهِ ﷺ قَالَ عُثْمَانُ وَبِي وَجَعٌ قَدْ كَادَ يُهْلِكُنِي فَقَالَ رَسُولُ اللهِ ﷺ أَمْسِكْ بِيَمِينِكَ سَبْعَ مَرَّاتٍ وَقُلْ أَعُوذُ بِعِزَّةِ اللهِ وَقُدْرَتِهِ مِنْ شَرِّ مَا أَجِدُ قَالَ فَفَعَلْتُ ذَلِكَ فَأَذْهَبَ اللهُ مَا كَانَ بِي فَلَمْ أَزَلْ آمُرُ بِهِ أَهْلِيوَغَيْرَهُمْ
