nasai:248ʿAmr b. ʿAlī > Yaḥyá > Hishām b. ʿUrwah from my father > ʿĀʾishah

'Aishah narrated concerning the Ghusl of the Prophet ﷺ from Janabah, that he used to wash his hands and perform Wudu', then he would run (his fingers) through his (hair on his) head so that it reaches all of his hair, then he would pour water over his entire body.  

النسائي:٢٤٨أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ قَالَ أَنْبَأَنَا يَحْيَى قَالَ أَنْبَأَنَا هِشَامُ بْنُ عُرْوَةَ قَالَ حَدَّثَنِي أَبِي قَالَ حَدَّثَتْنِي عَائِشَةُ ؓ

عَنْ غُسْلِ النَّبِيِّ ﷺ مِنَ الْجَنَابَةِ أَنَّهُ كَانَ يَغْسِلُ يَدَيْهِ وَيَتَوَضَّأُ وَيُخَلِّلُ رَأْسَهُ حَتَّى يَصِلَ إِلَى شَعْرِهِ ثُمَّ يُفْرِغُ عَلَى سَائِرِ جَسَدِهِ
