Hadith 1:42
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 َ (47)
