"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.  

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
