"The Messenger of Allah ﷺ came to me while I had a pain that almost ruined me. So,the Messenger of Allah ﷺ said: 'Rub it with your right hand seven times and say Aʿudhu bi ʿIzzatillah Wa Qudratihi wa Sultanihi min sharri ma ajid." ("I seek refuge in Allah's might, power, an authority, from the evil of what I suffer.)" He said: "So I did it, and Allah removed what I had, and I never ceased telling my family and others to do it." (Using translation from Tirmidhī 2080)
جَاءَنِي رَسُولُ اللهِ ﷺ يَعُودُنِي مِنْ وَجَعٍ اشْتَدَّ بِي فَقَالَ امْسَحْ بِيَمِينِكَ سَبْعَ مَرَّاتٍ وَقُلْ أَعُوذُ بِعِزَّةِ اللهِ وَقُدْرَتِهِ مِنْ شَرِّ مَا أَجِدُ فَفَعَلْتُ فَأَذْهَبَ اللهُ مَا كَانَ بِي فَلَمْ أَزَلْ آمُرُ بِهِ أَهْلِي وَغَيْرَهُمْ
