story and paragraph

 hello

I have a book in Arabic consisting of 1000 pages.

I have a problem with formatting

At the end of the story, I have a paragraph consisting of four lines.

The fourth line automatically moves to the next page

How do I make the fourth line go back to the same page?

Are there automatic settings?

For example, it automatically reduces the distance between Lines so that the fourth line returns to the same page.

I want a code to solve this problem
