Jabala bin Suhaim reported: Ibn Zubair used to provide us with dates during the time that the people were hard pressed because of famine (Once) as we were busy in eating there happened to appear before us Ibn 'Umar. He said: Don't eat two dates together, for Allah's Messenger (ﷺ) forbade eating them together but only after seeking permission from his brother (partner). Shu'bah said: I do not think these words pertaining to seeking permission but from the words of Ibn 'Urnar.
This hadith has been reported on the authority of Shu'bah with the same chain of transmitters but these words of his (are not found): "The people were hard pressed because of the famine during those days."
Jabala bin Suhaim reported: I heard Ibn 'Umar as saying that Allah's Messenger (ﷺ) forbade anyone taking two dates together without seeking the consent of his companions.
