Narrated Aisha: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."
حَدَّثَنَا آدَمُ، حَدَّثَنَا شُعْبَةُ، حَدَّثَنَا قَتَادَةُ، قَالَ سَمِعْتُ زُرَارَةَ بْنَ أَوْفَى، يُحَدِّثُ عَنْ سَعْدِ بْنِ هِشَامٍ، عَنْ عَائِشَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " مَثَلُ الَّذِي يَقْرَأُ الْقُرْآنَ وَهْوَ حَافِظٌ لَهُ مَعَ السَّفَرَةِ الْكِرَامِ الْبَرَرَةِ، وَمَثَلُ الَّذِي يَقْرَأُ الْقُرْآنَ وَهْوَ يَتَعَاهَدُهُ وَهْوَ عَلَيْهِ شَدِيدٌ، فَلَهُ أَجْرَانِ ".
