A drink (milk mixed with water) was brought to Messenger of Allah ﷺ who drank some of it. A boy was sitting to his right, and some old men to his left. Messenger of Allah ﷺ said to the boy, "Do you allow me to give the rest of the drink to these people?" The boy said, "O Messenger of Allah ﷺ! I will not give preference to anyone over me to drink the rest of it from which you have drunk." Messenger of Allah ﷺ then handed the bowl (of drink) to the boy. (See Hadith No. 541). (Using translation from Bukhārī 2451)  

أَنَّ رَسُولَ اللهِ ﷺ أُتِيَ بِشَرَابٍ فَشَرِبَ مِنْهُ وَعَنْ يَمِينِهِ غُلَامٌ وَعَنْ يَسَارِهِ الْأَشْيَاخُ فَقَالَ لِلْغُلَامِ «ائْذَنْ لِي أَنْ أُعْطِيَ هَؤُلَاءِ» فَقَالَ الْغُلَامُ «يَا رَسُولَ اللهِ لَا أُوثِرَ بِنَصِيبِي مِنْكَ أَحَدًا فَتَلَّهُ رَسُولُ اللهِ ﷺ فِي يَدِهِ»
