It is stated from Suleman ibne Ja’far that when one day he visited Imam Reza (a.s.), he saw a huge quantity of fresh dates kept before the Imam (a.s.) who was having the dates. When Suleman commented that Imam (a.s.) was helping himself to the dates quite generously, the Imam (a.s.) said that he liked the dates very much because they were liked by the Holy Prophet (s.a.w.a.), Hazrat Ali (a.s.), Imam Hasan (a.s.), Imam Husain (a.s.), Imam Zainul Abedeen (a.s.), Imam Mohammed Baqir (a.s.), Imam Ja’far-e-Sadiq (a.s.) and his father Imam Moosa Kazim (a.s.). All those who have accepted the faith of the Imam (a.s.) will like them as they are made from same matter and enemies of Imam (a.s.) and Ahlul Bait will like wine because they are made from fire.
