The following rules are observed when we report commands and requests.
Use a reporting verb like request, order, tell, advise, beseech, threaten, beg, implore, ask, propose and forbid.
Note that all of these verbs except propose must be followed by an object.
Commands and requests are usually reported using a to-infinitive.
That-clauses can also be used. Note that after certain verbs, only to-infinitives are possible. In the same way, after some reporting verbs, only that-clauses are possible.
You will also need to observe the rules for the change of tenses and pronouns.
