Allah knows best, but he is referring to a hadith of the Prophet.

ﷺ, he ascended the pulpit, he ascended the first step.

Then he said: O Allah, ameen. Then the lesson, he said: O Allah, ameen, three times. They said: We heard you say ameen three times before you ascended. He said: Jibril came to me.

He said: O Muhammad, may his nose be rubbed in dust, whoever reaches his parents or one of them and does not enter jannah, say ameen. I said ameen.

Then the sixth, he said: O Muhammad, say ameen. I said ameen. He said: Whoever reaches Ramadan and is not forgiven.

Yes, whoever reaches Ramadan and is not forgiven, okay, so what?

May his nose be rubbed in the dust. Yes, may the nose of the one who reaches Ramadan and is not forgiven be rubbed in the dust. Say ameen, so I said ameen.

Then he said the third: O Muhammad, may the nose of the one in whose presence you are mentioned and does not send prayers upon you be rubbed in the dust.

He said, "Say ameen." He asks, what is the connection between these three? Witnessing Ramadan.

Honoring parents and sending prayers upon the Prophet ﷺ. There is no necessary connection between the three, but he mentioned them here because they are important, for this reason. Yes, Allah knows best.
