I saw the Messenger of Allah ﷺ performing ablution. He wiped his head front and back, his temples and his ears once.  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَتَوَضَّأُ قَالَتْ فَمَسَحَ رَأْسَهُ وَمَسَحَ مَا أَقْبَلَ مِنْهُ وَمَا أَدْبَرَ وَصُدْغَيْهِ وَأُذُنَيْهِ مَرَّةً وَاحِدَةً  

she saw the Prophet performing Wudu. She said: "He wiped his head, and what is in the front of it and what is in its rear, and his temples and his ears one time."  

أَنَّهَا رَأَتِ النَّبِيَّ ﷺ يَتَوَضَّأُ قَالَتْ مَسَحَ رَأْسَهُ وَمَسَحَ مَا أَقْبَلَ مِنْهُ وَمَا أَدْبَرَ وَصُدْغَيْهِ وَأُذُنَيْهِ مَرَّةً وَاحِدَةً قَالَ وَفِي الْبَابِ عَنْ عَلِيٍّ وَجَدِّ طَلْحَةَ بْنِ مُصَرِّفِ بْنِ عَمْرٍو  

[Machine] The Messenger of Allah ﷺ performed ablution near it, and I saw him wiping over his head, from the beginning to the end of his hair, and he also wiped over his forehead, ears, and the visible and hidden parts of his ear lobes.  

أَنَّ رَسُولَ اللهِ ﷺ تَوَضَّأَ عِنْدَهَا فَرَأَيْتُهُ مَسَحَ عَلَى رَأْسِهِ مَجَارِيَ الشَّعْرِ مَا أَقْبَلَ مِنْهُ وَمَا أَدْبَرَ وَمَسَحَ صُدْغَيْهِ وَأُذُنَيْهِ ظَاهِرَهُمَا وَبَاطِنَهُمَا  

[Machine] I saw the Messenger of Allah ﷺ perform ablution, and he wiped the front of his head and the back of his head, and he wiped his temples and his ears, both their outer and inner parts, and their origins.  

رَأَيْتُ رَسُولَ اللهِ ﷺ يَتَوَضَّأُ فَمَسَحَ مَا أَقْبَلَ مِنْ رَأْسِهِ وَمَا أَدْبَرَ وَمَسَحَ صُدْغَيْهِ وَأُذُنَيْهِ ظَاهِرَهُمَا وَبَاطِنَهُمَا وَمَنْبَتَهُمَا
