وَحَدَّثَنِي عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا شُعْبَةُ، عَنْ عَاصِمٍ، سَمِعَ الشَّعْبِيَّ، سَمِعَ ابْنَ عَبَّاسٍ، قَالَ سَقَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم مِنْ زَمْزَمَ فَشَرِبَ قَائِمًا وَاسْتَسْقَى وَهُوَ عِنْدَ الْبَيْتِ ‏.‏

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