Muwatta Malik, Book 49, Hadith 1687 (In-Book) ⓘ
Yahya related to me from Malik from Ibn Shihab that A'isha, umm al-muminin and Sad ibn Abi Waqqas did not see any harm in a man drinking while standing.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، أَنَّ عَائِشَةَ أُمَّ الْمُؤْمِنِينَ، وَسَعْدَ بْنَ أَبِي وَقَّاصٍ، كَانَا لاَ يَرَيَانِ بِشُرْبِ الإِنْسَانِ وَهُوَ قَائِمٌ بَأْسًا .
