Virtues of the Qur'an
Bukhari :: Book 6 :: Volume 61 :: Hadith 579
Narrated Abu Musa:
The Prophet said, "The example of a believer who recites the Qur'an and acts on it, like a citron which tastes nice and smells nice. And the example of a believer who does not recite the Qur'an but acts on it, is like a date which tastes good but has no smell. And the example of a hypocrite who recites the Qur'an is like a Raihana (sweet basil) which smells good but tastes bitter And the example of a hypocrite who does not recite the Quran is like a colocynth which tastes bitter and has a bad smell."
