[Machine] The Prophet ﷺ used to perform ablution from impurity, then he would enter his right hand into the water and rub it on the right side of his head, following the roots of his hair. Then he would do the same with the left side of his head using his left hand. He would continue doing this until he covered his entire scalp. After that, he would pour water over his head three times.
أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَتَوَضَّأُ مِنَ الْجَنَابَةِ ثُمَّ يُدْخِلُ يَدَهُ الْيُمْنَى فِي الْمَاءِ ثُمَّ يُخَلِّلُ بِهَا شِقَّ رَأَسِهِ الْأَيْمَنِ فَيَتْبَعُ بِهَا أُصُولَ الشَّعْرِ ثُمَّ يَفْعَلُ بِشِقِّ رَأْسِهِ الْأَيْسَرِ بِيَدِهِ الْيُسْرَى كَذَلِكَ حَتَّى يَسْتَبْرِئَ الْبَشَرَةَ ثُمَّ يَصُبُّ عَلَى رَأْسِهَا ثَلَاثًا
