Musnad Ahmad 30:546

'Abd al-Razzaq narrated to us, Ma'mar informed us, from al-Zuhri, from Ibn al-Musayyib, from Abu Hurayrah, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Whatever you catch, pray it, and whatever you miss, complete it." Ma'mar said: "And he did not mention prostration."
