The Prophet (PBUH) passed away when we had our fill of the two black things: dates and water.

I asked Sahl ibn Sa'd: Did the Messenger of Allah (PBUH) ever eat refined barley? Sahl replied: The Messenger of Allah (PBUH) did not see refined barley from the time Allah sent him as a Prophet until he took his soul. I then asked: Did you have sieves in the time of the Messenger of Allah? He replied: The Messenger of Allah (PBUH) did not see a sieve from the time Allah sent him as a Prophet until He took his soul. I then asked: So how did you eat barley that was not sifted? He said: We used to grind it, blow on it, and what flew off, flew off. Then we would moisten the rest and eat it.
