Ibn 'Abbas reported that Messenger of Allah ﷺ drank (water) from Zamzam in a bucket while he was standing.

Ibn 'Abbas reported that Allah's Apostle ﷺ drank (water) from Zamzam while he was standing.

أَنَّ رَسُولَ اللَّهِ ﷺ شَرِبَ مِنْ زَمْزَمَ وَهُوَ قَائِمٌ

I served (water from) Zamzam to Messenger of Allah ﷺ, and he drank while standing, and he asked for it while he was near the House (i. e. House of Allah-Ka'ba).

سَقَيْتُ رَسُولَ اللَّهِ ﷺ مِنْ زَمْزَمَ فَشَرِبَ قَائِمًا وَاسْتَسْقَى وَهُوَ عِنْدَ الْبَيْتِ

This hadith is reported on the authority of Shu'ba with the same chain of transmitters but with a slight variation of wording.

عَنْ شُعْبَةَ بِهَذَا الإِسْنَادِ وَفِي حَدِيثِهِمَا فَأَتَيْتُهُ بِدَلْوٍ
