One has the experience the moment to believe it.

I don't for a moment believe he's in an impossible situation.

Besides, I do not for a moment believe that it was 'our' question at all.

He couldn't, for the moment, believe that it was real.

Do not for a moment believe that I share your fears or struggles.

I did not for a moment believe what he had told me.

He did not for a moment believe she would call him.

He did not for a moment believe it was coincidence they were on his tail.

And I don't for a moment believe they've come down to watch this next broadcast.

She did not for a moment believe it would be the Song-57 house.
