He prayed Zuhr, then sat attending to people's needs in the open courtyard of Kufa until the time for Asr prayer arrived. Then water was brought to him, and he drank from it and washed his face and hands. He also mentioned his head and feet. Then he stood up and drank what remained while standing, and said, "Some people dislike drinking while standing, but the Prophet ﷺ did exactly as I have done."
أنه صلى الظهر ثم قعد في حوائج الناس في رحبة الكوفة حتى حضرت صلاة العصر، ثم أتي بماء فشرب وغسل وجهه ويديه- وذكر رأسه ورجليه- ثم قام فشرب فضله وهو قائم، ثم قال: إن ناسا يكرهون الشرب قائما، وإن النبي ﷺ صنع مثل ما صنعت.
