The example of him

Narrated Abu Musa Al-Ash'ari (Radi-Allahu 'anhu):

The Prophet (Sallallahu 'Alaihi Wa Sallam) said, "The example of him (a
believer) who recites the Qur'an is like that of a citron which tastes good
and smells good. And he (a believer) who does not recite the Qur'an is like
a date which is good in taste but has no smell. And the example of a
dissolute wicked person who recites the Qur'an is like the Raihana (sweet
basil) which smells good but tastes bitter. And the example of a dissolute
wicked person who does not recite the Qur'an is like the colocynth which
tastes bitter and has no smell."
