佛說佛名經 16.39

16.39

馬頭羅剎答曰：「此諸沙門受佛淨戒而不畏罪，手擿眾僧菓自食與人不知慚愧。以是因緣，墮此地獄。從地獄出，若得為人瘖瘂不語。」

The horse-headed rākṣasa replied: 'These śramaṇas received the Buddha's pure precepts but did not fear sinning. With their own hands they plucked fruits belonging to the saṅgha, eating them themselves and giving them to others without feeling shame. Because of these causes and conditions, they fell into this hell. When they emerge from this hell, if they manage to become human, they will be mute and unable to speak.'
