If you wake up at Mghrib time, you should pray the missed prayer in order and then pray Maghrib, as long as you will pray Maghrib on time.

If you are going to pray Maghrib in the masjid, you can pray it first and then pray the missed prayers in order.

I am asking if you miss Fajr Salat and Duhr Salaat because you were sleeping. By the time you wake up its Magrib Salaat, do u pray magrib first than Fajr and duhr or do u pray fajr, dhur and than the magrib salaat?
