مُوَطَّأُ مَالِكٍ
Muwatta Malik 1689
The Description of the Prophet (ﷺ)
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ عَامِرِ بْنِ عَبْدِ اللَّهِ بْنِ الزُّبَيْرِ، عَنْ أَبِيهِ، أَنَّهُ كَانَ يَشْرَبُ قَائِمًا .
Yahya related to me from Malik from Amir ibn Abdullah ibn az- Zubayr that his father used to drink while standing.
