I told him to work hard.

Explanation ↴

When we want to report an order in indirect speech, we use different forms of words such as order, command, and tell. When we use reporting verbs such as order, command, or tell, no conjunction is used to introduce the reported speech. We do not say, I told him that to work hard.
