Musannaf Ibn Abi Shayba 22:137

Ibn Fudayl narrated to us, from al-Hasan ibn Ubayd Allah, from al-Musayyab ibn Rafi’, from Abu Salih, who said: The Qur’an will intercede for its companion on the Day of Resurrection, so he will be clothed with the garment of honor. He will say, "O Lord, increase him, for he has missed out." He said: So he will be clothed with the crown of honor. He said: He will say, "O Lord, increase him, for he has missed out." He will say, "My pleasure."
