the Prophet Muhammad said: "When performing Wudu go between the fingers."  

قَالَ النَّبِيُّ ﷺ إِذَا تَوَضَّأْتَ فَخَلِّلِ الأَصَابِعَ قَالَ وَفِي الْبَابِ عَنِ ابْنِ عَبَّاسٍ وَالْمُسْتَوْرِدِ وَهُوَ ابْنُ شَدَّادٍ الْفِهْرِيُّ وَأَبِي أَيُّوبَ الأَنْصَارِيِّ  

Messenger of Allah said: "When performing Wudu go between the fingers of your hands and (toes of) your feet."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا تَوَضَّأْتَ فَخَلِّلْ بَيْنَ أَصَابِعِ يَدَيْكَ وَرِجْلَيْكَ  

"I saw the Prophet when he was performing Wudu doing that to the toes on his feet with his pinky."  

رَأَيْتُ النَّبِيَّ ﷺ إِذَا تَوَضَّأَ دَلَكَ أَصَابِعَ رِجْلَيْهِ بِخِنْصَرِهِ
