[Machine] "O people, learn, for indeed one of you does not know when death will approach him." Then a man came to him and said, "O Abu 'Abdul Rahman, what do you say about a person who recites the Qur'an in a reversed manner?" He said, "That is a reflection of a corrupted heart." Then the man said, "And what if I bring a beautifully adorned and decorated Qur'an?" Abdullah (ibn Mas'ud) said, "Indeed, the best thing that a Qur'an is adorned with is reciting it with sincerity."  

«يَا أَيُّهَا النَّاسُ تَعَلَّمُوا فَإِنَّ أَحَدَكُمْ لَا يَدْرِي مَتَى يَحْتَلُّ إِلَيْهِ» فَجَاءَهُ رَجُلٌ فَقَالَ يَا أَبَا عَبْدِ الرَّحْمَنِ أَرَأَيْتَ رَجُلًا يَقْرَأُ الْقُرْآنَ مَنْكُوسًا؟ قَالَ «ذَلِكَ مَنْكُوسُ الْقَلْبِ» فَقَالَ وَأُتِيَ بِمُصْحَفٍ قَدْ زُيِّنَ وَذُهِّبَ فَقَالَ عَبْدُ اللهِ «إِنَّ أَحْسَنَ مَا زُيِّنَ بِهِ الْمُصْحَفُ تِلَاوَتُهُ فِي الْحَقِّ»
