Sahl b. Sa'd Sa'idi reported that Allah's Messenger (ﷺ) was given a drink, and he drank from that, and there was on his right side a boy. and on his left some old men. He said to the boy:
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 Allah's Messenger (ﷺ) then gave it in his hand.
