四分律比丘戒本 1.p143

1.p143

If a monk, at a time when the other monks are going through the form of religious expostulation, speak thus: “Excellent sirs! I cannot now learn this law. I purpose going to some one of eminent wisdom, who observes the precepts, to put some difficulties to him by way of query.” This is pācittiya. If there are any explanations necessary, they ought to be sought for at once.
