The proficient reciter of the Qur’an will be with the noble and obedient angel-scribes, and the one who recites the Qur’an stutteringly and finds it difficult will have two rewards

The Prophet (may Allah's peace and blessings be upon him) informed that the one who recites the Qur’an with strong memorization, precision, and proficiency will have the reward in the Hereafter of being in the rank of the noble and obedient angel-scribes.

As for the one who recites the Qur’an while stuttering and rehearsing in his recitation due to weak memorization, yet continues to maintain his connection with the Qur’an despite its difficulty for him, he will have two rewards: one reward for his recitation and another for the difficulty and his rehearsing in his recitation.
