The Prophet ﷺ was brought milk that was mixed with water. A nomad Arab was on his right and Abu Bakr was on his left. He himself drank and gave it to the nomad Arab, and said: He who is on the right , then he who is on his right then he who is on his right. (Using translation from Abū Dāʾūd 3726)
أَنَّ النَّبِيَّ ﷺ شَرِبَ وَعَنْ يَمِينِهِ أَعْرَابِيٌّ وَعَنْ يَسَارِهِ أَبُو بَكْرٍ فَنَاوَلَهُ الْأَعْرَابِيَّ وَقَالَ الْأَيْمَنَ فَالْأَيْمَنَ
