who has narrated the following: I said to Abu Abdullah (asws), ‘When one of us becomes ill, the healers order us to go on a diet’. So he (asws) said: ‘But, the People (asws) of the Household, we (asws) do not stay away except from the dates, and we (asws) cure by the apple and the cold water’. I said, ‘And why do you (asws) keep away from the dates?’ He (asws) said: ‘Because the Prophet (saww) of Allah (azwj) kept Ali (asws) away from it during his (asws) illness’.
