Narrated Abu Musaرضي الله عنه :

The prophetصلي الله عليه و سلم said,( The example of a believer who recites the Qu’ran and acts on it ,is like a citron which testes nice and smells nice. And the example of a believer who does not recite the Qu’ran but acts on it is like a date which tastes good but has no smell. And the example of a hypocrite who recites the Qu’ran is like a Raihana(sweet basil) which smells good but testes bitter.And the example of a hypocrite who does not recite the Qu’ran is like a colocynth which testes bitter and has a bad smell.)
