Musnad Abu Ya'la al-Mawsili 151:40

Muhammad ibn Abdullah ibn Numayr narrated to us, Muhammad ibn Abdullah ibn al-Zubayr narrated to us, from Yunus ibn Abi Ishaq, from Abi Ishaq, from Abi al-Ahwas, from Abdullah, who said: They used to recite behind the Prophet, may Allah bless him and grant him peace, in the prayer. So he said: "You have confused the Quran for me."
