Musannaf Ibn Abi Shayba 22:142

Affan narrated to us, he said: Hammam narrated to us, he said: Asim ibn Bahdala narrated to us, from al-Sha'bi, from Ibn Mas'ud, who said: The Quran will come on the Day of Resurrection and intercede for its companion, so it will be a leader for him to Paradise. And it will testify against him, so it will be a driver for him to the Fire.
