حَدَّثَنَا عَلِيُّ بْنُ إِسْحَاقَ حَدَّثَنَا عَبْدُ اللَّهِ أَخْبَرَنَا سُفْيَانُ عَنْ سِمَاكٍ عَنْ عِكْرِمَةَ عَنِ ابْنِ عَبَّاسٍ أَنَّ بَعْضَ أَزْوَاجِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اغْتَسَلَتْ مِنْ الْجَنَابَةِ فَتَوَضَّأَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِفَضْلِهِ فَذَكَرَتْ ذَلِكَ لَهُ فَقَالَ إِنَّ الْمَاءَ لَا يُنَجِّسُهُ شَيْءٌ
مسند امام احمد بن حنبل · Hadith 2102
It was narrated from Ibn 'Abbas (RA) that one of the wives of the Prophet (PBUH) did ghusl from janabah, and the Prophet (PBUH) did wudoo' with her left-over water. She said something about that to him and he said; "Nothing makes water najis (impure)’'
