That the Messenger of Allah (ﷺ) said: "The food of two is sufficient for three, and the food of three is sufficient for four."

He said: There are narrations on this topic from Jabir, and Ibn 'Umar.

This Hadith is Hasan Sahih.
Jami` at-Tirmidhi Book 25, Hadith 34
← Previous Hadith "The Messenger of Allah (ﷺ) had a disbeliever as a guest. So the Messenger of Allah (ﷺ) ordered that a sheep be milked so he could drink. Then another was milked so he could drink, then another, so he drank until he had drank the milk of seven sheep. The he awoke the next morning and accepted Islam. The Messenger of Allah (ﷺ) ordered that a sheep be milked so he could drink its milk, then he ordered for another but he could not finish it. So the Messenger of Allah (ﷺ) said: 'The believer drinks with one intestine and the disbeliever drinks with seven.'"

This Hadith is Sahih Hasan Gharib as a narration of Suhail.
