Islamic Interpretation of Dreams (Ibn-i Sirin):
(Crab apple; Crataegus azarolus; Mespilus germanica) Eating a bitter tasting applelike fruit of the medlar tree or any of such varieties that are also used in making preserves, or eaten yellow, spoiled, or unripened in a dream means a sickness.
The more yellowish is its color in the dream, the more pain and suffering such an sickness will bring. Eating a green medlar fruit in a dream represents no such danger. Eating any yellowish fruit in a dream represents a sickness, except for citron, apples, or the lotus fruit, for their yellow color in the dream does not cause any harm, since their substance is a viable medicinal cure.
