Narrated Aisha, Ummul Mu'minin:

Jumay' ibn Umayr, one of the sons of Banu Taym Allah ibn Tha'labah, said: Accompanied by my mother and aunt I entered upon Aisha. One of them asked her: How did you do while taking a bath? Aisha replied: The Messenger of Allah ﷺ performed ablution (in the beginning) as he did for prayer. He then poured (water) upon his head three times. But we poured water upon our heads five times due to plaits.

حَدَّثَنَا يَعْقُوبُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، - يَعْنِي ابْنَ مَهْدِيٍّ - عَنْ زَائِدَةَ بْنِ قُدَامَةَ، عَنْ صَدَقَةَ، حَدَّثَنَا جُمَيْعُ بْنُ عُمَيْرٍ، - أَحَدُ بَنِي تَيْمِ اللَّهِ بْنِ ثَعْلَبَةَ - قَالَ دَخَلْتُ مَعَ أُمِّي وَخَالَتِي عَلَى عَائِشَةَ فَسَأَلَتْهَا إِحْدَاهُمَا كَيْفَ كُنْتُمْ تَصْنَعُونَ عِنْدَ الْغُسْلِ فَقَالَتْ عَائِشَةُ كَانَ رَسُولُ اللَّهِ ﷺ يَتَوَضَّأُ وُضُوءَهُ لِلصَّلاَةِ ثُمَّ يُفِيضُ عَلَى رَأْسِهِ ثَلاَثَ مَرَّاتٍ وَنَحْنُ نُفِيضُ عَلَى رُءُوسِنَا خَمْسًا مِنْ أَجْلِ الضَّفْرِ .
