Sunan Ibn Majah 214
It was narrated from Abu Musa Al-Ash'ari that:
The Prophet said: "The likeness of the believer who recites the Qur'an is that of a citron, the taste and smell of which are good. The likeness 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 likeness of a hypocrite who reads the Qur'an is that of a sweet basil, the smell of which is good but its taste is bitter. And the likeness 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.'"
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، قَالاَ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنْ شُعْبَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، عَنْ أَبِي مُوسَى الأَشْعَرِيِّ، عَنِ النَّبِيِّ ـ صلى الله عليه وسلم ـ قَالَ ‏
"‏ مَثَلُ الْمُؤْمِنِ الَّذِي يَقْرَأُ الْقُرْآنَ كَمَثَلِ الأُتْرُجَّةِ طَعْمُهَا طَيِّبٌ وَرِيحُهَا طَيِّبٌ وَمَثَلُ الْمُؤْمِنِ الَّذِي لاَ يَقْرَأُ الْقُرْآنَ كَمَثَلِ التَّمْرَةِ طَعْمُهَا طَيِّبٌ وَلاَ رِيحَ لَهَا وَمَثَلُ الْمُنَافِقِ الَّذِي يَقْرَأُ الْقُرْآنَ كَمَثَلِ الرَّيْحَانَةِ رِيحُهَا طَيِّبٌ وَطَعْمُهَا مُرٌّ وَمَثَلُ الْمُنَافِقِ الَّذِي لاَ يَقْرَأُ الْقُرْآنَ كَمَثَلِ الْحَنْظَلَةِ طَعْمُهَا مُرٌّ وَلاَ رِيحَ لَهَا ‏"‏ ‏.‏
