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)
أَنَّ رَسُولَ اللَّهِ ﷺ تَوَضَّأَ فَمَسَحَ نَاصِيَتَهُ وَعِمَامَتَهُ وَعَلَى الْخُفَّيْنِ قَالَ بَكْرٌ وَقَدْ سَمِعْتُهُ مِنِ ابْنِ الْمُغِيرَةِ بْنِ شُعْبَةَ عَنْ أَبِيهِ
