Mishkat al-Masabih 21 Foods كتاب الأطعمة 110

وَعَنْ سَهْلِ بْنِ سَعْدٍ قَالَ: أَتَى النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِقَدَحٍ فَشَرِبَ مِنْهُ وَعَنْ يَمِينِهِ غُلَامٌ أَصْغَرُ الْقَوْمِ وَالْأَشْيَاخُ عَنْ يَسَارِهِ فَقَالَ: «يَا غُلَامُ أَتَأْذَنُ أَنْ أُعْطِيَهُ الْأَشْيَاخَ؟» فَقَالَ: مَا كُنْتُ لِأُوثِرَ بِفَضْلٍ مِنْكَ أَحَدًا يَا رَسُولَ اللَّهِ فَأعْطَاهُ إِيَّاه.

Sahl b. Sa’d told that the Prophet was brought a cup from which he drank, and on his right was a youth who was the youngest present, while the old men were on his left. He asked the youth to permit him to give it to the old men, but he replied, “I am not one to give anyone preference in a favour from you, messenger of God.” So he gave it to him. (Bukhari and Muslim.)
