"The Prophet ﷺ drank from Zamzam while he was standing." He said: There are narrations on this topic from 'Ali, Sa'd, 'Abdullah bin 'Amr and 'Aishah.  

أَنَّ النَّبِيَّ ﷺ شَرِبَ مِنْ زَمْزَمَ وَهُوَ قَائِمٌ قَالَ وَفِي الْبَابِ عَنْ عَلِيٍّ وَسَعْدٍ وَعَبْدِ اللَّهِ بْنِ عَمْرٍو وَعَائِشَةَ  

From his father, from his grandfather who said: "I saw the Messenger of Allah ﷺ drinking while standing and sitting."  

رَأَيْتُ رَسُولَ اللَّهِ ﷺ يَشْرَبُ قَائِمًا وَقَاعِدًا
