Aslam said to him, “The machine was working yesterday.”

Aslam asked him that the machine has been working the previous day.

Aslam told him that the machine had been working the previous day.

Aslam told him that the machine had been working yesterday.

None of these

In indirect speech, "was working" changes to "had been working," and "yesterday" changes to "the previous day."

The correct reporting verb "told" is used instead of "asked" for a statement.
