وَعَنْ عَلِيٍّ رَضِيَ اللَّهُ عَنْهُ: أَنَّهُ صَلَّى الظُّهْرَ ثُمَّ قَعَدَ فِي حَوَائِجِ النَّاسِ فِي رَحَبَةِ الْكُوفَةِ حَتَّى حَضَرَتْ صَلَاةُ الْعَصْرِ ثُمَّ أُتِيَ بِمَاءٍ فَشَرِبَ وَغَسَلَ وَجْهَهُ وَيَدَيْهِ وَذَكَرَ رَأسه وَرجلَيْهِ ثمَّ قَامَ فَشرب فَصله وَهُوَ قَائِمٌ ثُمَّ قَالَ: إِنَّ أُنَاسًا يَكْرَهُونَ الشُّرْبَ قَائِمًا وَإِنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَنَعَ مِثْلَ مَا صَنَعْتُ. رَوَاهُ الْبُخَارِيُّ
Ali, may Allah be pleased with him, prayed the noon prayer and then sat in the public square of Kufa attending to the needs of the people until the afternoon prayer was due. Water was brought to him, and he drank. He washed his face and hands, wiped his head and feet, then stood and drank again. He said, “Some people dislike drinking while standing, but the Prophet ﷺ did as I have just done.” Bukhari transmitted it.
