Do you permit me to give it to them (the old men), but that boy said: by God. I will not give preference at your hand over me in my share. He (the narrator) said that Messenger of Allah ﷺ then gave it in his hand. (Using translation from Muslim 2030a)
أَنَّ رَسُولَ اللهِ ﷺ أُتِيَ بِشَرَابٍ فَشَرِبَ مِنْهُ وَعَنْ يَمِينِهِ غُلَامٌ وَعَنْ يَسَارِهِ الْأَشْيَاخُ فَقَالَ لِلْغُلَامِ أَتَأْذَنُ لِي أَنْ أُعْطِيَ هَؤُلَاءِ؟ فَقَالَ لَا وَاللهِ لَا أُوثِرُبِنَصِيبِي مِنْكَ أَحَدًا قَالَ فَتَلَّهُ رَسُولُ اللهِ ﷺ فِي يَدِهِ
