Riyad us Saliheen: Hadith 993

The Messenger of Allah (ﷺ) 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].
