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).  

أَنَّ رَسُولَ اللَّهِ ﷺ أُتِيَ بِشَرَابٍ فَشَرِبَ مِنْهُ وَعَنْ يَمِينِهِ غُلاَمٌ وَعَنْ يَسَارِهِ الأَشْيَاخُ فَقَالَ لِلْغُلاَمِ أَتَأْذَنُ لِي أَنْ أُعْطِيَ هَؤُلاَءِ فَقَالَ الْغُلاَمُ لاَ وَاللَّهِ يَا رَسُولَ اللَّهِ لاَ أُوثِرُ بِنَصِيبِي مِنْكَ أَحَدًا قَالَ فَتَلَّهُ رَسُولُ اللَّهِ ﷺ فِي يَدِهِ
