The Prophet ﷺ said, 'The example of a believer who recites the Qur'an is that of a citron (a citrus fruit) which is good in taste and good in smell. And the believer who does not recite the Qur'an is like a date which has a good taste but no smell. And the example of an impious person who recites the Qur'an is that of Ar-Rihana (an aromatic plant) which smells good but is bitter in taste. And the example of an impious person who does not recite the Qur'an is that of a colocynth which is bitter in taste and has no smell."

عَنِ النَّبِيِّ ﷺ قَالَ مَثَلُ الْمُؤْمِنِ الَّذِي يَقْرَأُ الْقُرْآنَ كَالأُتْرُجَّةِ طَعْمُهَا طَيِّبٌ وَرِيحُهَا طَيِّبٌ وَالَّذِي لاَ يَقْرَأُ كَالتَّمْرَةِ طَعْمُهَا طَيِّبٌ وَلاَ رِيحَ لَهَا وَمَثَلُ الْفَاجِرِ الَّذِي يَقْرَأُ الْقُرْآنَ كَمَثَلِ الرَّيْحَانَةِ رِيحُهَا طَيِّبٌ وَطَعْمُهَا مُرٌّ وَمَثَلُ الْفَاجِرِ الَّذِي لاَ يَقْرَأُ الْقُرْآنَ كَمَثَلِ الْحَنْظَلَةِ طَعْمُهَا مُرٌّ وَلاَ رِيحَ لَهَا

Some people asked the Prophet ﷺ about soothsayers, and he said: "They are nothing." They said, "O Messenger of Allah, they speak of something that turns out to be true." He said: then the Prophet ﷺ said: "That word of truth is snatched by the jinni, who cackles it into the ear of his ally like the cackling of a hen, and they mix into it more than one hundred lies."

سَأَلَ أُنَاسٌ النَّبِيَّ ﷺ عَنِ الْكُهَّانِ، فَقَالَ: «إِنَّهُمْ لَيْسُوا بِشَىْءٍ». فَقَالُوا: يَا رَسُولَ اللَّهِ، فَإِنَّهُمْ يُحَدِّثُونَ بِالشَّىْءِ يَكُونُ حَقًّا. قَالَ: فَقَالَ النَّبِيُّ ﷺ: «تِلْكَ الْكَلِمَةُ مِنَ الْحَقِّ يَخْطَفُهَا الْجِنِّيُّ، فَيُقَرْقِرُهَا فِي أُذُنِ وَلِيِّهِ كَقَرْقَرَةِ الدَّجَاجَةِ، فَيَخْلِطُونَ فِيهِ أَكْثَرَ مِنْ مِائَةِ كَذْبَةٍ».

The Prophet ﷺ said, "There will emerge from the East some people who will recite the Qur'an but it will not exceed their throats and who will go out of (renounce) the religion (Islam) as an arrow passes through the game, and they will never come back to it unless the arrow, comes back to the middle of the bow (by itself) (i.e., impossible). The people asked, "What will their signs be?" He said, "Their sign will be the habit of shaving (of their beards and their heads). (Fath-ul-Bari, Page 322, Vol. 17th)

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ؓ عَنِ النَّبِيِّ ﷺ قَالَ يَخْرُجُ نَاسٌ مِنْ قِبَلِ الْمَشْرِقِ وَيَقْرَءُونَ الْقُرْآنَ لاَ يُجَاوِزُ تَرَاقِيَهُمْ يَمْرُقُونَ مِنَ الدِّينِ كَمَا يَمْرُقُ السَّهْمُ مِنَ الرَّمِيَّةِ ثُمَّ لاَ يَعُودُونَ فِيهِ حَتَّى يَعُودَ السَّهْمُ إِلَى فُوقِهِ قِيلَ مَا سِيمَاهُمْ قَالَ سِيمَاهُمُ التَّحْلِيقُ أَوْ قَالَ التَّسْبِيدُ
