How to Perform Ablution - Section 2
وَعَن الرّبيع بنت معوذ: أَنَّهَا رَأَتِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَتَوَضَّأُ قَالَتْ فَمَسَحَ رَأْسَهُ مَا أَقَبْلَ مِنْهُ وَمَا أَدْبَرَ وَصُدْغَيْهِ وَأُذُنَيْهِ مَرَّةً وَاحِدَةً وَفِي رِوَايَةٍ أَنَّهُ تَوَضَّأَ فَأَدْخَلَ أُصْبُعَيْهِ فِي جُحْرَيْ أُذُنَيْهِ. رَوَاهُ أَبُو دَاوُدَ وَرَوَى التِّرْمِذِيُّ الرِّوَايَةَ الأولى وَأحمد وَابْن مَاجَه الثَّانِيَة
Ar-Rubaiyi‘ daughter of Mu'awwidh said that she saw the Prophet (ﷺ) performing ablution, saying that he wiped his head front and back, his temples and his ears once. A version says that he performed ablution and inserted his two fingers in his ear-holes. Abu Dawud transmitted it. Tirmidhi transmitted the first version, and Ahmad and Ibn Majah the second.
