Musnad Abu Ya'la al-Mawsili 108:221

Ubayd Allah al-Qawariri narrated to us, Hammad narrated to us, from ‘Amr, from Jabir: That a man entered while the Messenger of Allah (may Allah bless him and grant him peace) was delivering the sermon to the people on Friday. He said, "Have you prayed, O so-and-so?" He said, "No." He said, "Then stand and pray."
