“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)
"إذَا نامَ أحدُكُمْ وفي يدِهِ ريحُ غَمَرٍ ، فلمْ يغْسلْ يدهُ، فأصَابَه شيءٌ فلا يلومُ إلّا نفْسَهُ".
