´`Abdullah bin Busr narrated:` “The Messenger of Allah (ﷺ) stayed with my father.” So he said: “We brought some food near him, so he ate from it, then he was brought dates, so he would eat it and cast the pit with his two fingers” - he joined between his forefinger and middle finger - Shu`bah said: “And that is what I think concerning it, if Allah wills.” - “and he cast the pit between two fingers, then he was brought drink, so he drank it and then passed it to the one on his right.” He said: “So my father said - as he took hold of the rein of his beast: ‘Supplicate for us.’ So he said: ‘O Allah, bless for them what You have provided them, and forgive them, and have mercy on them (Allāhumma bārik lahum fī mā razaqtahum waghfir lahum warḥamhum).’”
Hadith Referenceسنن ترمذي / كتاب الدعوات عن رسول الله صلى الله عليه وسلم / 3576
Abdullah bin Busr from Banu Sulaim said: The Messenger of Allah ﷺ came to my father and he was a guest with him. He offered food to him and brought hais. He then brought a drink which he drank and he gave it to the one on his right. He ate dried dates and began to put the kernels on the back of his ring finger and middle finger. When he got up, my father also got up, and held the rein of his mount. He said: Pray to Allah for me. He said: O Allah, bless them in what you provided them, and have mercy on them.

Benefits and Issues: ➊ It is clear from this hadith that the Noble Prophet (sallallahu alayhi wa sallam) did not put the eaten date pits back into the same vessel. Rather, he kept them separate because refined natures find such things very unpleasant. In the same way, breathing into a water vessel is also disliked by others.
➋ After drinking a beverage, he (sallallahu alayhi wa sallam) gave it to the one on his right.
➌ Honoring a person of virtue, just as the host honored the Messenger of Allah (sallallahu alayhi wa sallam), is a commendable act.
➍ A host may request his guest to make supplication (du'a) for him.
➎ Making supplication (du'a) after eating is Sunnah. And it is best to make the very supplication that the Messenger of Allah (sallallahu alayhi wa sallam) made.
