Narrated Ibn 'Abbas: The Prophet ﷺ drank Zamzam (water) while standing.
The act of drinking from the well of Zamzam while standing is a sign of humility as it shows that one does not need any special treatment or privilege in order to receive something good or beneficial from Allah SWT. It also serves as a reminder that no matter how powerful or influential someone may be, they are still subject to Allah's laws and commands just like everyone else. Additionally, this hadith encourages people to appreciate all blessings bestowed upon them by Allah SWT and never take them for granted as these blessings are only given out of His mercy and kindness towards mankind.
