Is it obligatory to repeat the current Maghrib prayer after making up a missed Fajr prayer, if the Fajr prayer was not from the same day?

If you remember a missed prayer after performing a current prayer, you must make up the missed prayer immediately, and there is no need to repeat the current prayer, based on the Prophet's (peace be upon him) saying: "Whoever forgets a prayer, let him pray it when he remembers it; there is no expiation for it except that."

However, if you remember a missed prayer during a current prayer, there is a difference of opinion among jurists: Abu Hanifa and Malik: The current prayer becomes void, so one should pray the missed prayer first, then the current one. Shafi'is: One should complete the current prayer, then make up the missed prayer, and it is recommended to repeat the current prayer. Ahmad: One should complete the current prayer, then make up the missed prayer, and then repeat the current prayer obligatorily.

Repeating the current prayer in this situation is more preferable and cautious.
