[50] Now at that time bhikkhus, with bowl in hand, pushed open a door-panel. The bowl, swinging against the door-panel, broke. They reported this matter to the Blessed One. … "Bhikkhus, a door-panel should not be pushed open by a bhikkhu with bowl in hand; whoever should push one open commits an offence of wrong-doing (dukkaṭa)."
