حَدَّثَنَا أَحْمَدُ بْنُ مَنِيعٍ، قَالَ‏:‏ حَدَّثَنَا هُشَيْمٌ، قَالَ‏:‏ حَدَّثَنَا عَاصِمٌ الأَحْوَلُ، وَمُغِيرَةُ، عَنِ الشَّعْبِيِّ، عَنِ ابْنِ عَبَّاسٍ‏:‏ أَنَّ النَّبِيَّ صلى الله عليه وسلم، شَرِبَ مِنْ زَمْزَمَ، وَهُوَ قَائِمٌ‏.‏

Ibn 'Abbas said (may Allah be well pleased with him and his father)

"When the Prophet drank (Allah bless him and give him peace), he used to take two breaths.”
