Anas reported Allah's Apostle ﷺ disapproved the drinking of water while standing.

أَنَّ النَّبِيَّ ﷺ زَجَرَ عَنِ الشُّرْبِ قَائِمًا

that Allah's Apostle ( ﷺ) forbade that a person should drink while standing. Qatada reported: We said to him: What about eating? Thereupon he (Anas) said: That is even worse and more detestable (abominable).

عَنِ النَّبِيِّ ﷺ أَنَّهُ نَهَى أَنْ يَشْرَبَ الرَّجُلُ قَائِمًا قَالَ قَتَادَةُ فَقُلْنَا فَالأَكْلُ فَقَالَ ذَاكَ أَشَرُّ أَوْ أَخْبَثُ

This hadith is reported on the authority of Anas with a different chain of transmitters, but no mention is made of the words of Qatada.

عَنِ النَّبِيِّ ﷺ بِمِثْلِهِ وَلَمْ يَذْكُرْ قَوْلَ قَتَادَةَ

Abu Sa'id Khudri reported that Messenger of Allah ﷺ warned against drinking while standing.

أَنَّ النَّبِيَّ ﷺ زَجَرَ عَنِ الشُّرْبِ قَائِمًا

Abu Sa'id Khudri reported this hadith through another chain of transmitters but with a slight, variation of wording.

أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى عَنِ الشُّرْبِ قَائِمًا

None of you should drink while standing; and if anyone forgets, he must vomit.

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَشْرَبَنَّ أَحَدٌ مِنْكُمْ قَائِمًا فَمَنْ نَسِيَ فَلْيَسْتَقِئْ
