One of the wives of the Prophet ﷺ took a bath from a large bowl. The Prophet ﷺ wanted to perform ablution or take from the water left over. She said to him: O Prophet of Allah, verily I was sexually defiled. The Prophet said: Water not defiled. (Using translation from Abū Dāʾūd 68)
اغْتَسَلَ بَعْضُ أَزْوَاجِ النَّبِيِّ ﷺ فِي جَفْنَةٍ فَجَاءَ النَّبِيُّ ﷺ لِيَتَوَضَّأَ مِنْهَا أَوْ لِيَغْتَسِلَ فَقَالَتْ لَهُ يَا رَسُولَ اللهِ إِنِّي كُنْتُ جُنُبًا فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّ الْمَاءَ لَا يَنْجُسُ»
