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
She saw the Prophet (sallallahu alayhi wa sallam) 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.
