Musnad Ahmad 132:37

Hassan narrated to us, Ibn Lahi'ah narrated to us, Zabban narrated to us, from Sahl, from his father, from the Messenger of Allah (peace and blessings of Allah be upon him) that he said: "Whoever says: 'Glory be to Allah, the Almighty' (Subhan Allah al-Azim), a plant is planted for him in Paradise. And whoever recites the Quran, completes it, and acts upon what is in it, his parents will be clothed on the Day of Resurrection with a crown that is more beautiful than the light of the sun in the houses of the houses of this world, if it were in them. So what do you think of the one who acted upon it?"
