Muwatta Imam Malik Book of The Description of the Prophet ﷺ, Hadith 15

Yahya related to me from Malik that Abu Jafar al-Qari said, "I saw Abdullah ibn Umar drink while standing."

وَحَدَّثَنِي مَالِكٌ، عَنْ أَبِي جَعْفَرٍ الْقَارِيِّ، أَنَّهُ قَالَ رَأَيْتُ عَبْدَ اللَّهِ بْنَ عُمَرَ يَشْرَبُ قَائِمًا .
