Narrated Qatadah:
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ ، حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ ، عَنْ سَعِيدِ بْنِ أَبِي عَرُوبَةَ ، عَنْ قَتَادَةَ ، عَنْ أَنَسٍ ، أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى أَنْ يَشْرَبَ الرَّجُلُ قَائِمًا . فَقِيلَ الأَكْلُ قَالَ ذَاكَ أَشَدُّ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
From Anas: "The Prophet (ﷺ) prohibited that a man should drink while standing." (Qatadah said:) So it was said: "And eating ?" He (Anas) said: "That is worse." [Abu 'Eisa said:] This Hadith is Hasan Sahih.
