وَعَنْ عَبْدِ اَللَّهِ بْنِ يَزِيدَ بْنِ عَاصِمٍ رضى الله عنه (فِي صِفَةِ اَلْوُضُوءِ)
قَالَ: «وَمَسَحَ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِرَأْسِهِ، فَأَقْبَلَ بِيَدَيْهِ وَأَدْبَرَ»
The Messenger of Allah (sallallahu alayhi wa sallam) wiped his head from the forehead to the back of his head and then back to the forehead with his (wet) hands.
