Then the people ceased (to recite behind the imam).Another version says: Sufyan said: Al-Zuhri spoke a word that I could not hear. Then Ma'mar said; He said: Then people ceased (to recite the Qur'an)

This version has: Al-Zuhri said: The Muslims took lesson from that and thenceforth they did not recite (the Qur'an) at the prayer in which he (the Prophet) recited a loud.
Abu Dawud said: I heard Muhammad b. Yaya b. Faris say: The words " the people ceased to recite (the Qur'an)" is a statement of al-zuhri.
