四分律比丘含注戒本 1.496

1.496

The Buddha was in Kapilavastu. The group of six bhikṣus took sheep's wool and had a bhikṣuṇī wash, dye, and card it. At that time, the maternal aunt bhikṣuṇī had dyed hands from dyeing wool; she went to the Buddha's place, bowed at his feet, and stood there. The Buddha asked although he already knew, rebuked them, and laid down the precept.
