It was narrated from Al-Mughirah that the Prophet ﷺ performed Wudu', and he wiped the forehead, the 'Imamah, and over the Khuff. (Another chain) (Using translation from Nasāʾī 107)
أَنَّ رَسُولَ اللهِ ﷺ «تَوَضَّأَ فَمَسَحَ نَاصِيَتَهُ وَعِمَامَتَهُ وَعَلَى الْخُفَّيْنِ» قَالَ بَكْرٌ وَقَدْ سَمِعْتُهُ مِنَ ابْنِ الْمُغِيرَةِ
