The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، وَعَلِيَّ بْنَ أَبِي طَالِبٍ، وَعُثْمَانَ بْنَ عَفَّانَ، كَانُوا يَشْرَبُونَ قِيَامًا .
Yahya related to me from Malik that he had heard that Umar ibn
al-Khattab and Ali ibn Abi Talib and Uthman ibn Affan drank while
standing.
