Sahih al-Bukhari 2602
Narrated Sahl bin Sa`d:
A drink (milk mixed with water) was brought to the Prophet (ﷺ) who drank some of it while a boy was 
sitting on his right and old men on his left. The Prophet (ﷺ) said to the boy, "If you permit me, I'll give 
(the rest of the drink to) these old men first." The boy said, "I will not give preference to any one over 
me as regards my share from you, O Allah's Messenger (ﷺ)!" The Prophet (ﷺ) then put that container in the boy's 
hand. (See Hadith No. 541).
حَدَّثَنَا يَحْيَى بْنُ قَزَعَةَ، حَدَّثَنَا مَالِكٌ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ ـ رضى الله عنه ـ أَنَّ النَّبِيَّ صلى الله عليه وسلم أُتِيَ بِشَرَابٍ فَشَرِبَ، وَعَنْ يَمِينِهِ غُلاَمٌ وَعَنْ يَسَارِهِ الأَشْيَاخُ فَقَالَ لِلْغُلاَمِ ‏
"‏ إِنْ أَذِنْتَ لِي أَعْطَيْتُ هَؤُلاَءِ ‏"‏‏.‏ فَقَالَ مَا كُنْتُ لأُوثِرَ بِنَصِيبِي مِنْكَ يَا رَسُولَ اللَّهِ أَحَدًا‏.‏ فَتَلَّهُ فِي يَدِهِ‏.‏
