حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا أَبُو الأَحْوَصِ، حَدَّثَنَا سِمَاكٌ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ اغْتَسَلَ بَعْضُ أَزْوَاجِ النَّبِيِّ صلى الله عليه وسلم فِي جَفْنَةٍ فَجَاءَ النَّبِيُّ صلى الله عليه وسلم لِيَتَوَضَّأَ مِنْهَا - أَوْ يَغْتَسِلَ - فَقَالَتْ لَهُ يَا رَسُولَ اللَّهِ إِنِّي كُنْتُ جُنُبًا ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ إِنَّ الْمَاءَ لاَ يَجْنُبُ ‏"‏ ‏.‏

Narrated Abdullah ibn Abbas: One of the wives of the Prophet (PBUH) took a bath from a large bowl. The Prophet (PBUH) 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. Translation Not Available
