The Prophet ﷺ said, "Such a person as recites the Qur'an and masters it by heart, will be with the noble righteous scribes (in Heaven). And such a person exerts himself to learn the Qur'an by heart, and recites it with great difficulty, will have a double reward."  

عَنِ النَّبِيِّ ﷺ قَالَ مَثَلُ الَّذِي يَقْرَأُ الْقُرْآنَ وَهْوَ حَافِظٌ لَهُ مَعَ السَّفَرَةِ الْكِرَامِ الْبَرَرَةِ وَمَثَلُ الَّذِي يَقْرَأُ الْقُرْآنَ وَهْوَ يَتَعَاهَدُهُ وَهْوَ عَلَيْهِ شَدِيدٌ فَلَهُ أَجْرَانِ  

[Machine] The Prophet ﷺ said: "The example of the one who recites the Quran and memorizes it, while he is diligent in it, is like that of two rewards. And the example of the one who recites the Quran and memorizes it, while it is difficult for him, is like that of noble, righteous traveling companions."  

عَنِ النَّبِيِّ ﷺ قَالَ مَثَلُ الَّذِي يَقْرَأُ الْقُرْآنَ وَيَتَعَاهَدُهُ وَهُوَ عَلَيْهِ شَدِيدٌ فَلَهُ أَجْرَانِ قَالَ وَمَثَلُ الَّذِي يَقْرَأُ الْقُرْآنَ وَهُوَ حَافِظٌ مَثَلُ السَّفَرَةِ الْكِرَامِ الْبَرَرَةِ  

One who is skilled in the Qur'an is associated with the noble, upright recording angels, and he who falters when he recites the Qur'an and finds it difficult for him will have a double reward. (Using translation from Abū Dāʾūd 1454)  

عَنِ النَّبِيِّ ﷺ قَالَ «مَثَلُ الَّذِي يَقْرَأُ الْقُرْآنَ وَهُوَ مَاهِرٌ بِهِ مَعَ السَّفَرَةِ الْكِرَامِ الْبَرَرَةِ وَالَّذِي يَقْرَؤُهُ وَهُوَ عَلَيْهِ شَاقٌّ فَلَهُ أَجْرَانِ»  

"مثل الَّذي يقرأُ الْقرآنَ وهو ماهرٌ به مع السفرةِ الكرام البررة والذي يقرأُه وهو يشْتَدُّ عليه له أَجْرانَ".
