The ruling on one who enters the mosque while they are praying Maghrib and has not yet prayed 'Asr

Question:
This questioner has another question in which he says: I entered the mosque and the Maghrib prayer was being performed, and I had not yet prayed 'Asr. Should I pray 'Asr after Maghrib, or should I pray 'Asr first and then Maghrib? Or should I join the imam while he is praying Maghrib, complete the fourth rak'ah, and that would suffice for 'Asr? Please advise us, may Allah reward you.

Answer:
If a person has 'Asr due on him and the time for Maghrib prayer arrives, he should pray Maghrib with them and complete it with a fourth rak'ah with the intention of 'Asr, then pray Maghrib afterwards. He is excused according to the correct opinion in this issue. The reason for adding the fourth rak'ah is that 'Asr consists of four rak'ahs. When the imam says the taslim, he stands up and completes the prayer like one who joined late, and it suffices for him. He is not permitted to precede Maghrib with 'Asr because the order is obligatory. Arranging the prayers—praying 'Asr, then Maghrib, then 'Isha'—is a necessary matter, just as Allah (Glorified and Exalted is He) made them obligatory .
When the prayers were missed by the Prophet (peace and blessings be upon him) on the Day of the Trench until the sun had set, he began with 'Asr and prayed it, then prayed Maghrib afterwards.
And in a narration: .
The point is that he maintains the order: he prays Maghrib with them with the intention of 'Asr. When the imam says the taslim, he stands up and prays the fourth rak'ah, and it suffices for him. Then he prays 'Isha' in its time. However, if he is able to pray 'Asr before that by arriving before the iqamah is called, let him begin with 'Asr, pray it, and then pray Maghrib with them. Yes.
