Jabir b. 'Abdullah reported:I heard Allah'. s Messenger (ﷺ) as saying: Food for one person suffices two persons and food for two persons suffices four persons, and food for four persons suffices eight persons; and in the tradition transmitted on the authority of Ishaq there is no mention of the fact that he heard it directly (from the Holy Prophet)

A hadith like this is reported on the authority of Jabir but with a different chain of transmitters

Jabir reported Allah's Messenger (ﷺ) as saying:Food for one suffices two and food for two suffices for four

Jabir reported Allah's Messenger (ﷺ) as saying:Food for one (person) suffices two, and food for two (persons) suffices four persons and food for four persons suffices eight persons
