Sahadhaṁmikavagga

Vinayapiṭaka · Parivāra · Vol. 8 · Section 371

[371] Having given a robe together with a united Saṅgha, one who afterwards engages in criticizing (khīyanadhamma) commits two offenses (āpatti): while he is criticizing, there is an offense of wrong-doing (dukkaṭa) in the act; when the criticizing is completed, there is an offense entailing expiation (pācittiya).
