✅ Answer: To answer this question, we will present a general principle from Imam Baqir (peace be upon him) that can also be applied to similar situations, such as when both Maghrib and Isha prayers are missed until the time for Fajr prayer arrives, or in any case when a prayer is missed until the time for the next prayer comes.

The principle from our master, Imam Baqir (peace be upon him):

✅عَنِ الْقَاسِمِ بْنِ عُرْوَةَ عَنْ عُبَیْدِ بْنِ زُرَارَةَ عَنْ أَبِیهِ عَنْ أَبِی جَعْفَرٍ قَالَ إِذَا فَاتَتْکَ صَلَاةٌ فَذَکَرْتَهَا فِی وَقْتٍ أُخْرَی فَإِنْ کُنْتَ تَعْلَمُ أَنَّکَ إِذَا صَلَّیْتَ الَّتِی فَاتَتْکَ کُنْتَ مِنَ الْأُخْرَی فِی وَقْتٍ فَابْدَأْ بِالَّتِی فَاتَتْکَ فَإِنَّ اللَّهَ عَزَّ وَ جَلَّ یَقُولُ أَقِمِ الصَّلاةَ لِذِکْرِی وَ إِنْ کُنْتَ تَعْلَمُ أَنَّکَ إِذَا صَلَّیْتَ الَّتِی فَاتَتْکَ فَاتَتْکَ الَّتِی بَعْدَهَا فَابْدَأْ بِالَّتِی أَنْتَ فِی وَقْتِهَا وَ اقْضِ الْأُخْرَی

Imam Baqir (peace be upon him) said: When a prayer is missed, and you remember it at the time of the next prayer, if you know that performing the missed prayer will not cause the current prayer time to be lost, then perform the missed prayer first, because Allah says in the Qur'an, 'Establish the prayer for My remembrance.' However, if you know that performing the missed prayer will cause you to miss the current prayer, then perform the current prayer first and make up the missed one afterward.

✅ Note: It should be noted that this principle applies when you are in the time for a prayer and have missed the previous prayer for any reason. In this case, if there is enough time, perform the missed prayer first and then perform the current prayer.

Inshallah.
