حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، عَنْ عَلْقَمَةَ بْنِ مَرْثَدٍ، عَنْ سَعْدِ بْنِ عُبَيْدَةَ، عَنْ أَبِي عَبْدِ الرَّحْمَنِ، عَنْ عُثْمَانَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ خَيْرُكُمْ مَنْ تَعَلَّمَ الْقُرْآنَ وَعَلَّمَهُ ‏"‏ ‏.‏
Translation
'Aishah reported the Prophet (ﷺ) 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.
