Musannaf Ibn Abi Shaybah

Hazrat Amr bin Murrah narrates that Hazrat Mujahid said: The Qur'an will intercede for its reciter on the Day of Judgment. It will say: O my Lord! You placed me in his chest, so I kept him awake at night, and I kept him away from many desires. And every laborer receives the reward for his work. Then it will be said to that person: Stretch out your hand. The narrator says: Then his hand will be filled with Allah's pleasure and approval, after which He will never be displeased with him. Then it will be said to that memorizer of the Qur'an: Keep reciting and keep ascending. Then for every verse, his rank will be elevated, and for every verse, an additional good deed will be granted.
