Narrated Sahl bin Sa`d: Once a tumbler (full of milk or water) was brought to Allah's Apostle who drank from it, while on his right side there was sitting a boy who was the youngest of those who were present, and on his left side there were old men. The Prophet asked, "O boy! Do you allow me to give (the drink) to the elder people (first)?" The boy said, "I will not prefer anybody to have my share from you, O Allah's Apostle!" So, he gave it to the boy.
