Sahih (Sahih al-Bukhari)
حَدَّثَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أُتِيَ بِشَرَابٍ، وَعَنْ يَمِينِهِ غُلاَمٌ وَعَنْ يَسَارِهِ أَشْيَاخٌ، فَقَالَ لِلْغُلاَمِ " أَتَأْذَنُ لِي أَنْ أُعْطِيَ هَؤُلاَءِ ". فَقَالَ الْغُلاَمُ لاَ، وَاللَّهِ لاَ أُوثِرُ بِنَصِيبِي مِنْكَ أَحَدًا. فَتَلَّهُ فِي يَدِهِ.

He asked the boy, "Will you allow me to give it to these (people)?" The boy said, "No, by Allah, I will not allow anyone to take my right from you." Then the Prophet put the bowl in the boy's hand
