Hadith 4:28
It was narrated that 'Aishah said:
"When the Messenger of Allah (ﷺ0 performed Ghusl from Janabah, he would wash his hands, then perform Wudu' as for prayer, then run his fingers through his hair until he was sure the water had reached the scalp, then he would pour water over his head three times, then wash the rest of his body."
أَخْبَرَنَا عَلِيُّ بْنُ حُجْرٍ، قَالَ حَدَّثَنَا عَلِيُّ بْنُ مُسْهِرٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ غَسَلَ يَدَيْهِ ثُمَّ تَوَضَّأَ وُضُوءَهُ لِلصَّلاَةِ ثُمَّ يُخَلِّلُ رَأْسَهُ بِأَصَابِعِهِ حَتَّى إِذَا خُيِّلَ إِلَيْهِ أَنَّهُ قَدِ اسْتَبْرَأَ الْبَشَرَةَ غَرَفَ عَلَى رَأْسِهِ ثَلاَثًا ثُمَّ غَسَلَ سَائِرَ جَسَدِهِ
