[Machine] In the Torah, it is mentioned that the blessing of food is ablution before and after it. I mentioned this to the Prophet ﷺ and he said that the blessing of food is ablution before and after it. Qais bin Rabi'ah is not strong and there is no evidence in the hadith about washing the hands before eating.  

البيهقي:١٤٦٠٤ – أَخْبَرَنَا أَبُو بَكْرٍ مُحَمَّدُ بْنُ الْحُسَيْنِ بْنِ فُورَكٍ أنا عَبْدُ اللهِ بْنُ جَعْفَرٍ نا يُونُسُ بْنُ حَبِيبٍ نا أَبُو دَاوُدَ الطَّيَالِسِيُّ نا قَيْسٌ هُوَ ابْنُ الرَّبِيعِ عَنْ أَبِي هَاشِمٍ عَنْ زَاذَانَ عَنْ سَلْمَانَ قَالَ

فِي التَّوْرَاةِ إِنَّ بَرَكَةَ الطَّعَامِ الْوُضُوءُ قَبْلَهُ فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ بَرَكَةُ الطَّعَامِ الْوُضُوءُ قَبْلَهُ وَبَعْدَهُ قَيْسُ بْنُ الرَّبِيعِ غَيْرُ قَوِيٍّ وَلَمْ يَثْبُتْ فِي غَسْلِ الْيَدِ قَبْلَ الطَّعَامِ حَدِيثٌ

abudawud:3761 – Mūsá b. Ismāʿīl > Qays > Abū Hāshim > Zādhān > Salmān

I read in the Torah that the blessing of food consists in ablution before it. So I mentioned it to the Prophet ﷺ. He said: The blessing of food consists in ablution before it and ablution after it. Sufyan disapproved of performing ablution before taking food. Abu Dawud said: It is weak.  

أبو داود:٣٧٦١ – حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ حَدَّثَنَا قَيْسٌ عَنْ أَبِي هَاشِمٍ عَنْ زَاذَانَ عَنْ سَلْمَانَ قَالَ قَرَأْتُ فِي التَّوْرَاةِ

أَنَّ بَرَكَةَ الطَّعَامِ الْوُضُوءُ قَبْلَهُ فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ بَرَكَةُ الطَّعَامِ الْوُضُوءُ قَبْلَهُ وَالْوُضُوءُ بَعْدَهُ وَكَانَ سُفْيَانُ يَكْرَهُ الْوُضُوءَ قَبْلَ الطَّعَامِ

tirmidhi:1846 – [Chain 1] Yaḥyá b. Mūsá > ʿAbdullāh b. Numayr > Qays b. al-Rabīʿ [Chain 2] Qutaybah > ʿAbd al-Karīm al-Jurjānī > Qays b. al-Rabīʿ al-Maʿná Wāḥid > Abū Hāshim / al-Rummānī > Zādhān > Salmān > Qaraʾt

"I read in the Tawrah that the blessing for food is in the Wudu' after it. So I mentioned that to the Prophet ﷺ, telling him what I read in the Tawrah. So the Messenger of Allah ﷺ said: 'The food's blessing is in the Wudu' before it and the Wudu' after it.'" He said: There are narrations on this topic from Anas and Abu Hurairah.  

[Abu 'Eisa said:] We do not know of this Hadith except as a narration of Qais bin Ar-Rabi'. Qais [bin Ar-Rabi'] was graded weak in Hadith. Abu Hashim Ar-Rumani's (a narrator in the chain) name is Yahya bin Dinar.
الترمذي:١٨٤٦ – حَدَّثَنَا يَحْيَى بْنُ مُوسَى حَدَّثَنَا عَبْدُ اللَّهِ بْنُ نُمَيْرٍ حَدَّثَنَا قَيْسُ بْنُ الرَّبِيعِ ح قَالَ وَحَدَّثَنَا قُتَيْبَةُ حَدَّثَنَا عَبْدُ الْكَرِيمِ الْجُرْجَانِيُّ عَنْ قَيْسِ بْنِ الرَّبِيعِ الْمَعْنَى وَاحِدٌ عَنْ أَبِي هَاشِمٍ يَعْنِي الرُّمَّانِيَّ عَنْ زَاذَانَ عَنْ سَلْمَانَ قَالَ قَرَأْتُ فِي التَّوْرَاةِ

أَنَّ بَرَكَةَ الطَّعَامِ الْوُضُوءُ بَعْدَهُ فَذَكَرْتُ ذَلِكَ لِلنَّبِيِّ ﷺ فَأَخْبَرْتُهُ بِمَا قَرَأْتُ فِي التَّوْرَاةِ فَقَالَ رَسُولُ اللَّهِ ﷺ بَرَكَةُ الطَّعَامِ الْوُضُوءُ قَبْلَهُ وَالْوُضُوءُ بَعْدَهُ قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ وَأَبِي هُرَيْرَةَ  

قَالَ أَبُو عِيسَى لاَ نَعْرِفُ هَذَا الْحَدِيثَ إِلاَّ مِنْ حَدِيثِ قَيْسِ بْنِ الرَّبِيعِ وَقَيْسُ بْنُ الرَّبِيعِ يُضَعَّفُ فِي الْحَدِيثِ وَأَبُو هَاشِمٍ الرُّمَّانِيُّ اسْمُهُ يَحْيَى بْنُ دِينَارٍ
