Arabic hadith text
وَعَنْ عَائِشَةَ قَالَتْ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَغْسِلُ رَأْسَهُ بِالْخِطْمِيِّ وَهُوَ جُنُبٌ يَجْتَزِئُ بِذَلِكَ وَلَا يَصُبُّ عَلَيْهِ الْمَاءَ. رَوَاهُ أَبُو دَاوُد
Translation
ʿĀʾisha said: ‘When in a state of sexual impurity, the Prophet would wash his head with khitmi, contenting himself with that and not pouring water over it.’ Abū Dāwūd transmitted it.
