Imam Ibnu Majah : 438حَدَّثَنَا مُحَمَّدُ بْنُ زِيَادٍ أَنْبَأَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ سِنَانِ بْنِ رَبِيعَةَ عَنْ شَهْرِ بْنِ حَوْشَبٍ عَنْ أَبِي أُمَامَةَأَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْأُذُنَانِ مِنْ الرَّأْسِ وَكَانَ يَمْسَحُ رَأْسَهُ مَرَّةً وَكَانَ يَمْسَحُ الْمَأْقَيْنِ
Narrated to us Muhammad bin Ziyad, narrated to us Hammad bin Zaid, from Sinan bin Rabi'ah, from Syahr bin Hausyab, from Abu Umamah, he said: The Messenger of Allah (peace and blessings be upon him) said: 'The ears are part of the head.' And he wiped his head once and wiped the earlobes.
