To what extent is the hadith "No one will enter Paradise until they come after you, O Muhammad" authentic?

The hadith "No one will enter Paradise until they come behind you, O Muhammad" has no origin, but its meaning is correct. Ibn al-Qayyim mentioned Junayd's saying, may Allah have mercy on him: "Allah Almighty says to His Messenger, peace and blessings be upon him: 'By My Honor and My Majesty, if they were to come to Me from every path, and seek to open every door, I would not open for them until they enter behind you.'"
