Nazal bin Sabra reported,

We prayed the noon prayer with Ali , then he went to a sitting place of his in the open courtyard. He sat down and we sat around him. When the time for the afternoon prayer came, a vessel was brought to him. He took a handful from it, rinsed his mouth, drew water into his nose, wiped his face and forearms, wiped his head, and wiped his feet. Then he stood up and drank what was left in the vessel.Then he said, "I have been told that some men consider it disliked for one of them to drink while standing. I saw the Messenger of Allah ﷺ do exactly as I have done."

حدثنا عبد الله حدثني أبو خيثمة وحدثنا إسحاق بن إسماعيل قالا حدثنا جرير عن منصور عن عبد الملك بن ميسرة

عن النزال بن سبرة قال

صلينا مع علي رضي الله عنه الظهر فانطلق إلى مجلس له يجلسه في الرحبة فقعد وقعدنا حوله ثم حضرت العصر فأتي بإناء فأخذ منه كفا فتمضمض واستنشق ومسح بوجهه وذراعيه ومسح برأسه ومسح برجليه ثم قام فشرب فضل إنائه ثم قال إني حدثت أن رجالا يكرهون أن يشرب أحدهم وهو قائم إني رأيت رسول الله ﷺ فعل كما فعلت
