Musannaf Ibn Abi Shayba 3:2721

Abu Usama narrated to us, from Abu al-Umays, from Ali ibn al-Aqmar, who said: Masruq, Urwah ibn al-Mughirah, and a group of the companions of Abdullah went out. The time for Friday prayer arrived, but they did not perform the Friday prayer. The time for Fitr (the day of Eid) arrived, but they did not break their fast.
