Musannaf Ibn Abi Shayba 3:1398

Ibn ‘Ulayyah narrated to us, from Ibn Jurayj, from al-‘Ala’ ibn ‘Abd al-Rahman ibn Ya‘qub, that Abu al-Sa’ib informed him, saying: I said to Abu Hurayrah, "I am behind the Imam." He pinched my arm and said, "O Persian, recite it to yourself," meaning the Mother of the Qur’an (al-Fatiha).
