It was narrated that Anas bin Malik said:
"When the Messenger of Allah performed ablution, he ran his fingers through his beard and separated his fingers (to let water run through them) twice."

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ حَفْصِ بْنِ هِشَامِ بْنِ زَيْدِ بْنِ أَنَسِ بْنِ مَالِكٍ، حَدَّثَنَا يَحْيَى بْنُ كَثِيرٍ أَبُو النَّضْرِ، صَاحِبُ الْبَصْرِيِّ عَنْ يَزِيدَ الرَّقَاشِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَ رَسُولُ اللَّهِ ـ ﷺ ـ إِذَا تَوَضَّأَ خَلَّلَ لِحْيَتَهُ وَفَرَّجَ أَصَابِعَهُ مَرَّتَيْنِ .
