“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.” (Using translation from Ibn Mājah 3297)
عَنِ النَّبِيِّ ﷺ قَالَ إِذَا بَاتَ أَحَدُكُمْ وَفِي يَدِهِ غَمَرٌ فَأَصَابَهُ شَيْءٌ فَلَا يَلُومَنَّ إِلَّا نَفْسَهُ
