Just as it is unpleasant to gossip about someone else's bad actions, it is even worse to pay attention to such gossip.
However, it's difficult to tell someone else, "Silence! I don't want to hear it." So, consider this:
There will come a time when an angel will want to report on your actions on Earth. How one behaves down here is how one is treated from above. If you had the nerve to respond this way, God will also say, "Silence! I don't want to hear it.".
