Once a tumbler (full of milk or water) was brought to Messenger of Allah ﷺ who drank from it, while on his right side there was sitting a boy who was the youngest of those who were present, and on his left side there were old men. The Prophet ﷺ asked, "O boy ! Do you allow me to give (the drink) to the elder people (first)?" The boy said, "I will not prefer anybody to have my share from you, O Allah's Apostle!" So, he gave it to the boy.
أُتِيَ رَسُولُ اللَّهِ ﷺ بِقَدَحٍ فَشَرِبَ وَعَنْ يَمِينِهِ غُلاَمٌ هُوَ أَحْدَثُ الْقَوْمِ وَالأَشْيَاخُ عَنْ يَسَارِهِ قَالَ يَا غُلاَمُ أَتَأْذَنُ لِي أَنْ أُعْطِيَ الأَشْيَاخَ فَقَالَ مَا كُنْتُ لأُوثِرَ بِنَصِيبِي مِنْكَ أَحَدًا يَا رَسُولَ اللَّهِ فَأَعْطَاهُ إِيَّاهُ
