[Machine] The Messenger of Allah, ﷺ , said: "Hearts are of four types: a heart that is pure like a lamp that shines brightly, a heart that is enclosed within a sheath, a heart that is inverted, and a heart that is hypocritical. As for the pure heart, it is the heart of a believer, and its light is his guidance. As for the heart that is enclosed within a sheath, it is the heart of a disbeliever. As for the inverted heart, it is the heart of a hypocrite that recognizes the truth but denies it. And as for the hypocritical heart, it is a heart that contains both belief and hypocrisy. The example of belief in it is like a fresh green pea, irrigated by pure water, while the example of hypocrisy in it is like a sore that exudes pus and blood. So, which of the two will overcome the other, will dominate it."

قَالَ رَسُولُ اللهِ ﷺ الْقُلُوبُ أَرْبَعَةٌ قَلْبٌ أَجْرَدُ فِيهِ مِثْلُ السِّرَاجِ يَزْهَرُ وَقَلْبٌ أَغْلَفُ مَرْبُوطٌ عَلَى غِلَافِهِ وَقَلْبٌ مَنْكُوسٌ وَقَلْبٌ مُصْفَحٌ فَأَمَّا الْقَلْبُ الْأَجْرَدُ فَقَلْبُ الْمُؤْمِنِ سِرَاجُهُ فِيهِ نُورُهُ وَأَمَّا الْقَلْبُ الْأَغْلَفُ فَقَلْبُ الْكَافِرِ وَأَمَّا الْقَلْبُ الْمَنْكُوسُ فَقَلْبُ الْمُنَافِقِ عَرَفَ ثُمَّ أَنْكَرَ وَأَمَّا الْقَلْبُ الْمُصْفَحُ فَقَلْبٌ فِيهِ إِيمَانٌ وَنِفَاقٌ فَمَثَلُ الْإِيمَانِ فِيهِ كَمَثَلِ الْبَقْلَةِ يَمُدُّهَا الْمَاءُ الطَّيِّبُ وَمَثَلُ النِّفَاقِ فِيهِ كَمَثَلِ الْقُرْحَةِ يَمُدُّهَا الْقَيْحُ وَالدَّمُ فَأَيُّ الْمَدَّتَيْنِ غَلَبَتْ عَلَى الْأُخْرَى غَلَبَتْ عَلَيْهِ
