Sunan Abi Dawud, Hadith 1449 ⓘ
'Aishah reported the Prophet as saying: 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.
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا هِشَامٌ، وَهَمَّامٌ، عَنْ قَتَادَةَ، عَنْ زُرَارَةَ بْنِ أَوْفَى، عَنْ سَعْدِ بْنِ هِشَامٍ، عَنْ عَائِشَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " الَّذِي يَقْرَأُ الْقُرْآنَ وَهُوَ مَاهِرٌ بِهِ مَعَ السَّفَرَةِ الْكِرَامِ الْبَرَرَةِ وَالَّذِي يَقْرَؤُهُ وَهُوَ يَشْتَدُّ عَلَيْهِ فَلَهُ أَجْرَانِ " .
