"The Prophet [SAW] said: 'The parable of the believer who recites the Qur'an is that of a citron, the taste and smell of which are good. The parable of a believer who does not read the Qur'an is that of a date, the taste of which is good but it has no smell. The parable of a hypocrite who reads the Qur'an is that of basil, the smell of which is good but its taste is bitter. And the parable of a hypocrite who does not read the Qur'an is that of a colocynth (bitter-apple), the taste of which is bitter and it has no smell.'" (Using translation from Nasāʾī 5038)  

عَنِ النَّبِيِّ ﷺ قَالَ «مَثَلُ الْمُؤْمِنِ الَّذِي يَقْرَأُ الْقُرْآنَ مَثَلُ الْأُتْرُجَّةِ طَعْمُهَا طَيِّبٌ وَرِيحُهَا وَمَثَلُ الْمُؤْمِنِ الَّذِي لَا يَقْرَأُ الْقُرْآنَ مَثَلُ التَّمْرَةِ طَعْمُهَا طَيِّبٌ وَلَا رِيحَ لَهَا وَمَثَلُ الْمُنَافِقِ الَّذِي يَقْرَأُ الْقُرْآنَ كَمَثَلِ الرَّيْحَانِ رِيحُهَا طَيِّبٌ وَطَعْمُهَا مُرٌّ وَمَثَلُ الْمُنَافِقِ الَّذِي لَا يَقْرَأُ الْقُرْآنَ مَثَلُ الْحَنْظَلِ طَعْمُهَا خَبِيثٌ وَرِيحُهَا»  

Messenger of Allah ﷺ said, "The example of a Believer who recites the Qur'an, is that of a citron which smells good and tastes good; And the example of a Believer who does not recite the Qur'an, is that of a date which has no smell but tastes sweet; and the example of a hypocrite who recites the Qur'an, is that of an aromatic plant which smells good but tastes bitter; and the example of a hypocrite who does not recite the Qur'an, is that of a colocynth plant which has no smell and is bitter in taste." (Using translation from Bukhārī 5427)  

قَالَ رَسُولُ اللهِ ﷺ «مَثَلُ الْمُؤْمِنِ الَّذِي يَقْرَأُ الْقُرْآنَ مَثَلُ الْأُتْرُجَّةِ رِيحُهَا طَيِّبٌ وَطَعْمُهَا طَيِّبٌ وَمَثَلُ الْمُؤْمِنِ الَّذِي لَا يَقْرَأُ الْقُرْآنَ كَمَثَلِ التَّمْرَةِ لَا رِيحَ لَهَا وَطَعْمُهَا حُلْوٌ وَمَثَلُ الْمُنَافِقِ الَّذِي يَقْرَأُ الْقُرْآنَ كَمَثَلِ الرَّيْحَانَةِ رِيحُهَا طَيِّبٌ وَطَعْمُهَا مُرٌّ وَمَثَلُ الْمُنَافِقِ الَّذِي لَا يَقْرَأُ الْقُرْآنَ كَمَثَلِ الْحَنْظَلَةِ لَيْسَ لَهَا رِيحٌ وَطَعْمُهَا مُرٌّ»
