Jami` at-Tirmidhi 3576

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).’”
