In which sutta does a lay disciple of the Buddha tell a non-buddhist mendicant that he has experienced jhana?

I remember reading a sutta some time ago in which a lay disciple of the Buddha held a conversation with a non-Buddhist ascetic. I don't remember the topic of their conversation, but at one point the lay buddhist talked about having experienced jhana. Does anyone know which sutta this is? Thanks in advance for your answers!
