Narrated Abdullah bin ‘Amr (rad) regarding the description of the ablution:

“Then he (Allah’s Messenger (ﷺ)) wiped his head, inserted his index finger in his ears and wiped the exterior of his ears with thumbs”. [Reported by Abu Da’ud and An-Nasa’i and Ibn Khuzaima graded it Sahih (sound)].

وَعَنْ عَبْدِ اَللَّهِ بْنِ عَمْرٍو رَضِيَ اَللَّهُ عَنْهُمَا ‏-فِي صِفَةِ اَلْوُضُوءِ‏- قَالَ: { ثُمَّ مَسَحَ ‏- صلى الله عليه وسلم ‏-بِرَأْسِهِ, وَأَدْخَلَ إِصْبَعَيْهِ اَلسَّبَّاحَتَيْنِ فِي أُذُنَيْهِ, وَمَسَحَ بِإِبْهَامَيْهِ ظَاهِرَ أُذُنَيْهِ.‏ } أَخْرَجَهُ أَبُو دَاوُدَ, وَالنَّسَائِيُّ, وَصَحَّحَهُ اِبْنُ خُزَيْمَة َ [1]‏ .‏
