Musannaf Ibn Abi Shayba 3:4726

Waki’ narrated to us, from Musafir al-Jassas, from Fudayl ibn ‘Amr, that ‘Adi ibn Thabit and some companions of his returned from a funeral and entered a mosque in which [the prayer] had already been performed, so they performed the prayer in congregation. Ibrahim disliked that.
