If Allah Had One Message for Humanity, What Would It Be?

A scene from a TV series has gone viral on social media. They ask in that scene, if Allah had a message for all mankind, what would it be? My question is this. If God had one message for us, if He sent us a single message that is very important for all of us, and it was just one line, what do you think it would be? What would Allah say if He had a message for all mankind? Wish to reach Me. Isn't it right? What do you say? That's the secret of the universe. Because if everyone has this wish, does everyone get the guarantee of the first floor of heaven? Yes. This is His message, God willing. May Allah bless you all.
