四分律比丘含注戒本 1.620

1.620

As for non-offenses: if he did not know; if he perceived it as not promised; if a little was promised and he encouraged them to give more; if it was promised to few persons and he encouraged them to give to many persons; if he encouraged them to give good items; if it was said in jest; or if he spoke in error—none of these are offenses.
