Hadith 568
Sahl bin Sa'd (May Allah be pleased with him) reported:
وعن سهل بن سعد رضي الله عنه أن رسول الله صلى الله عليه وسلم أتي بشراب، فشرب منه وعن يمينه غلام، وعن يساره الأشياخ، فقال للغلام:” أتأذن لى أن أعطي هؤلاء؟” فقال الغلام لا والله يا رسول الله، لا أؤثر منك أحداً، فتله رسول الله صلى الله عليه وسلم فى يده . ((متفق عليه)) . “تله” بالتاء المثناه، فوق ، أى وضعه، وهذا الغلام هو ابن عباس رضي الله عنهما.
A drink was brought to the Messenger of Allah (ﷺ) and he drank some of it. On his right was a boy and on his left were elderly people. He said to the boy, "Would you permit me to give the rest of this drink to these on my left?" The boy said, "O Messenger of Allah, I would certainly not give preference to anyone in anything that might come to me from you." So he handed over the rest of the drink to him. [Al- Bukhari and Muslim].
In plain words
Offered the leftover drink the Prophet had touched, a young boy would not give up his turn to anyone, treasuring even a small share that came from the Prophet's hand.
