5427. Narrated Abū Mūsā Al-Ash'arī: Allāh's Messenger ﷺ said, “The example of a believer who recites the Qur'ān (and acts on its orders), is that of a citron which smells good and tastes good; and the example of a believer who does not recite the Qur'ān (but acts on its orders), is that of a date which has no smell but tastes sweet; and the example of a hypocrite who recites the Qur'ān (and does not acts on its orders), is that of Ar-Raihān (an aromatic plant) which smells good but tastes bitter; and the example of a hypocrite who does not recite the Qur'ān (nor acts on its orders), is that of a colocynth plant which has no smell and is bitter in taste.” (See Fath Al-Bari for details)
