الترمذي:٣٣حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ عَنْ عَبْدِ اللَّهِ بْنِ مُحَمَّدِ بْنِ عَقِيلٍ عَنِ الرُّبَيِّعِ بِنْتِ مُعَوِّذِ بْنِ عَفْرَاءَ

أَنَّ النَّبِيَّ ﷺ مَسَحَ بِرَأْسِهِ مَرَّتَيْنِ بَدَأَ بِمُؤَخَّرِ رَأْسِهِ ثُمَّ بِمُقَدَّمِهِ وَبِأُذُنَيْهِ كِلْتَيْهِمَا ظُهُورِهِمَا وَبُطُونِهِمَا  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ وَحَدِيثُ عَبْدِ اللَّهِ بْنِ زَيْدٍ أَصَحُّ مِنْ هَذَا وَأَجْوَدُ إِسْنَادًا وَقَدْ ذَهَبَ بَعْضُ أَهْلِ الْكُوفَةِ إِلَى هَذَا الْحَدِيثِ مِنْهُمْ وَكِيعُ بْنُ الْجَرَّاحِ
