Bro, Its my humble suggestion that avoid to translate urdu into english. When You`re communicating in english just keep urdu aloof. So far as it is concerned with your query. They structure may use alike.

The usual forms of Have to :

We`re very busy at the office. I have to work on saturday morning
Ali has to get the car repaired.
Aisha had to go to the dentist yesterday

In other structures we can also use a form of have to, but not must :

Infinitives : I don`t want to have to wait in a queue for ages
After a modal verb : Sana has toothache. She might have to go to the dentist.
Present perfect : Khurram has had to drive all the way to Hyderabad.

You`re always welcome for your queries but I counsel u to purchase a worthy grammar book.

Take care,
