Prophet ﷺ said: “The example of a believer who recites the Qurʿān is that of a citron (a citrus fruit) which tastes good and smells good.

And the believer who does not recite the Qurʿān is like a date which tastes good but has no smell.

And the example of an evil person who recites the Qurʿān is that of Ar-Rihana (an aromatic plant) which smells good but tastes bitter.

And the example of an evil person who does not recite the Qurʿān is that of a colocynth which tastes bitter and has no smell.”
