Sunan Abi Dawud, Book 27, Hadith 3843 (USC-MSA) ⓘ
Narrated AbuHurayrah: The Prophet said: If anyone spends the night with grease on his hand which he has not washed away, he can blame only himself if some trouble comes to him.
حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا سُهَيْلُ بْنُ أَبِي صَالِحٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ نَامَ وَفِي يَدِهِ غَمَرٌ وَلَمْ يَغْسِلْهُ فَأَصَابَهُ شَىْءٌ فَلاَ يَلُومَنَّ إِلاَّ نَفْسَهُ " .
