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 النَّبِيَّ ﷺ أُتِيَ بِشَرَابٍ فَشَرِبَ مِنْهُ وَعَنْ يَمِينِهِ غُلَامٌ وَعَنْ شِمَالِهِ الْأَشْيَاخُ فَقَالَ لِلْغُلَامِ أَتَأْذَنُ فِي أَنْ أُعْطِيَهُ هَؤُلَاءِ؟ فَقَالَ وَاللهِ يَا رَسُولَ اللهِ مَا كُنْتُ لِأُوثِرَ بِنَصِيبِي مِنْكَ أَحَدًا
