Mujahid (may Allah have mercy on him) says: The Qur'an will intercede for its companion on the Day of Resurrection and will say: "O my Lord! You placed me in his chest, I kept him awake at night, and I restrained him from many desires, and every doer is given a reward!" Then (Allah Almighty) will say: "Stretch out your hand!" or He said: "Stretch out your right hand!" Then his hand will be filled with the pleasure of Allah, and He will never be displeased with him. Then it will be said: "Recite and ascend!" For every verse, his rank will be raised by one degree, and for every verse, he will be given a good deed.
