This was said by the Buddha, the Perfected One: that is what I heard.

“Mendicants, I’ve seen beings who engaged in misconduct by body, speech, and mind, who denounced the noble ones, who had wrong views and acted accordingly. At the breaking up of the body, after death, they were reborn in a place of loss, a bad place, the underworld, hell.

Now, I don’t say this because I’ve heard it from some other ascetic or brahmin. I only say it because I’ve known, seen, and realized it for myself.”

The Buddha spoke this matter. On this it is said:

“When the mind has been misdirected, 
and words wrongly spoken, 
and wrong bodily deeds have been done, 
a person here 

unlearned, doer of bad deeds, 
though their life may be short, 
when their body breaks up, that witless person 
is reborn in hell.”

This too is a matter that was spoken by the Blessed One: that is what I heard.
