How to make up the missed portion of the Maghrib prayer

Q: From Sh. 'A. M. - An Egyptian working in the Eastern Province. I sometimes pray with the imam, but I only catch one rak'ah of the Maghrib prayer. After the imam says the taslim, I stand up and perform the second rak'ah with al-Fatihah and a surah aloud, then I sit for the tashahhud and perform the third rak'ah aloud, and then I sit. Is my prayer valid or not?

A: Your prayer is valid, and reciting aloud in the second rak'ah is prescribed, but it should not be loud so as not to disturb the praying or dhikr-reciting people around you. As for the last rak'ah, you do not recite aloud in it because it is a secret rak'ah. You caught the beginning of the prayer, and the rak'ah you caught with the imam is the first of your prayer according to the correct opinion, and what you make up is the last of it. And success is from Allah.
