I gave the Prophet (may Allah's peace and blessings be upon him) Zamzam water to drink and he drank while standing

عن ابن عباس رضي الله عنهما قال: سَقَيْتُ النبيَّ صلى الله عليه وسلم مِنْ زَمْزَمَ، فَشَرِبَ وهو قَائِمٌ. عن النَّزَّالِ بنِ سَبْرَةَ رضي الله عنه قال: أَتَى عَلِيٌّ رضي الله عنه بَابَ الرَّحَبَةِ، فَشَرِبَ قَائِمًا، وقال: إِنِّي رأيتُ رسولَ اللهِ صلى الله عليه وسلم فَعَلَ كَمَا رَأَيْتُمُونِي فَعَلْتُ. عن عمرو بن شُعّيْبٍ، عن أبيه، عن جَدِّهِ رضي الله عنه قال: رأيتُ رسولَ اللهِ صلى الله عليه وسلم يَشْرَبُ قَائِمًا وقَاعِدًا.
