Riyad as-Salihin, Book 9, Hadith 994 (In-Book) ⓘ

'Aishah (May Allah be pleased with her) reported: The Messenger of Allah said, "The one who is proficient in the recitation of the Qur'an will be with the honourable and obedient scribes (angels) and he who recites the Qur'an and finds it difficult to recite, doing his best to recite it in the best way possible, will have a double reward."[Al-Bukhari and Muslim].

وعن عائشة رضي الله عنها قالت‏:‏ قال رسول الله صلى الله عليه وسلم ‏:‏ ‏ "‏الذي يقرأ القرآن وهو ماهر به مع السفرة الكرام البررة، والذي يقرأ القرآن ويتتعتع فيه وهو عليه شاق له أجران‏" ‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏
