Double rewards

Aishah r.a. reported:

The Messenger of Allah s.a.w. said, "The one who is proficient in the recitation of the Quran will be with the honourable and obedient scribes (angels) and he who recites the Quran finds it difficult to recite, doing his best to recite it in the best way possible, will have a double reward."
