[Machine] The Messenger of Allah ﷺ said, "Whoever sleeps with impurity in his hand and does not wash it, and something happens to him, he has no one to blame but himself." And the hadith of Suwaid bin Nu'man regarding the rinsing of the mouth of the Messenger of Allah ﷺ and their rinsing after eating Sawiq is evidence for this matter. It has already been mentioned in the Book of Taharah (purification). The hadith regarding washing hands after eating is good if it is done before eating, and it is weak if it is done after eating. And in the authentic hadith narrated by Ibn Abbas, the Prophet ﷺ went to the restroom and then came back, and food was brought to him. It was said, "O Messenger of Allah, shouldn't you perform ablution?" He said, "I haven't prayed, so I will perform ablution."  

قَالَ رَسُولُ اللهِ ﷺ مَنْ نَامَ وَفِي يَدِهِ غَمَرٌ وَلَمْ يَغْسِلْهُ فَأَصَابَهُ شَيْءٌ فَلَا يَلُومَنَّ إِلَّا نَفْسَهُ وَحَدِيثُ سُوَيْدِ بْنِ النُّعْمَانِ فِي مَضْمَضَةِ رَسُولِ اللهِ ﷺ وَمَضْمَضَتِهِمْ بَعْدَ أَكْلِهِمُ السَّوِيقَ دَلِيلٌ فِي هَذَا الْبَابِ وَقَدْ مَضَى فِي كِتَابِ الطَّهَارَةِ فَالْحَدِيثُ فِي غَسْلِ الْيَدِ بَعْدَ الطَّعَامِ حَسَنٌ وَهُوَ قَبْلَ الطَّعَامِ ضَعِيفٌ وَفِي الْحَدِيثِ الصَّحِيحِ عَنِ ابْنِ عَبَّاسٍ ؓ أَنَّ النَّبِيَّ ﷺ أَتَى الْخَلَاءَ ثُمَّ رَجَعَ فَأُتِيَ بِطَعَامٍ فَقِيلَ يَا رَسُولَ اللهِ أَلَا تَتَوَضَّأْ؟ فَقَالَ لَمْ أُصَلِّ فَأَتَوَضَّأَ
