It was narrated from Abu Hurairah that the Prophet ﷺ said:
“If anyone of you goes to bed with a smell emanating from his hand, and he does not wash his hand, and something happens to him, he should not blame anyone but himself.”

حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الْمَلِكِ بْنِ أَبِي الشَّوَارِبِ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ الْمُخْتَارِ، حَدَّثَنَا سُهَيْلُ بْنُ أَبِي صَالِحٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ ﷺ قَالَ " إِذَا نَامَ أَحَدُكُمْ وَفِي يَدِهِ رِيحُ غَمَرٍ فَلَمْ يَغْسِلْ يَدَهُ فَأَصَابَهُ شَىْءٌ فَلاَ يَلُومَنَّ إِلاَّ نَفْسَهُ " .
