The Long Āgama Sūtra 7.21

7.21

婆羅門言：「迦葉！我有親族知識，遇患困病，我往問言：『諸沙門、婆羅門各懷異見，言諸有殺生、盜竊、邪婬、兩舌、惡口、妄言、綺語、貪取、嫉妬、邪見者，身壞命終，皆入地獄。我初不信，所以然者？初未曾見死已來還，說所墮處。若有人來說所墮處，我必信受。汝今是我所親，十惡亦備，若如沙門語者，汝死必入大地獄中，今我相信，從汝取定，若審有地獄者，汝當還來，語我使知，然後當信。』迦葉！彼命終已，至今不來，彼是我親，不應欺我，許而不來，必無後世。」

The priest said, “Kāśyapa, I had a relative who fell seriously ill. I went and said to him, ‘Ascetics and priests each hold unorthodox views. They say that someone who kills beings, steals, engages in wrong sex, speaks duplicitously, uses harsh words, speaks falsely, speaks frivolously, or is greedy, jealous, and has wrong views will go to Hell when their body breaks up and their life ends. From the start, I haven’t believed this. Why is that? To begin with, I’ve never seen anyone return after dying, though it’s claimed they fall somewhere. If someone were to come back and say where they fell, I would certainly believe it. Now, you are a friend of mine who has done the ten bad deeds. If it’s as the ascetics say, you’ll surely go to a great Hell when you die. We trust each other, and I’d certainly accept what I heard from you. If you discover there is a hell, you should return and tell me about it. Then, I’ll believe it.’

“Kāśyapa, my relative hasn’t come back to me since their life ended. They were my friend; they wouldn’t have lied to me. They agreed, but they didn’t come back. Surely, there’s no afterlife.”
