Should one pray 'Ishā' then Maghrib, or the reverse, if Maghrib was missed and the time for 'Ishā' began and the 'Ishā' prayer was called?

Missed prayers must be made up immediately and in their original order, based on the hadith: "Pray as you have seen me praying." If it is not possible to pray Maghrib before Isha, one can join the congregation for Isha prayer with the intention of Maghrib. Upon completing the third rak'ah for Maghrib, the worshipper waits for the Imam to sit and then performs the taslim with him. A difference in intention between the Imam and the follower does not affect the prayer. If the time for the present prayer is short, it must be offered first, because in such a case, maintaining the order would lead to delaying the prayer beyond its prescribed time, which is impermissible. Evidence for the obligation of observing the order is that the Prophet, peace and blessings be upon him, prayed the obligatory prayers in order on the Day of Al-Ahzab after sunset. It is recommended to maintain prayers within their prescribed times.
