Jami` at-Tirmidhi Book 25, Hadith 64

"Banu Murrah bin 'Ubaid sent me to bring the Sadaqah from their wealth of the Messenger of Allah (ﷺ). I arrived with him in Al-Madinah and found him sitting between the Muhajirin and the Ansar." He said: "Then he took my hand and brought me to the home of Umm Salamah and he said: 'Do you have any food?' So a bowl containing a lot of Tharid with pieces of meat was brought to us, and presented for us to eat from it. So I began wandering my around it while the Messenger of Allah (ﷺ) ate from what was in front of him. He grabbed my right hand with his left hand, then he said: 'O 'Ikrash! Eat from one spot, for indeed the food is one.' Then a plate containing various dried dates" - or fresh dates - 'Ubaidullah (a narrator) was not sure. He said: "I began eating what was in front of me, while the hand of the Messenger of Allah (ﷺ) roamed about the plate. He said: 'O 'Ikrash! Eat from wherever you like, for indeed it is not all from the same variety.' Then water was brought, so the Messenger of Allah (ﷺ) washed his hands, and with the wetness of his hands he wiped his face, his forearms, and his head, and he said: 'O Ikrash! This is the Wudu' for that which has been altered by fire.'"

This Hadith is Gharib, we do not know of it except through the narration of Al-'Ala' bin Al-Fadl, and Al-Ala'was alone with this narration, and there is more in the story in the Hadith. And we do not know a Hadith from the Prophet (ﷺ) by 'Ikrash except this.
