If you catch up with the imam in the final tashahhud of a loud prayer and a man comes and prays behind you, do you recite aloud?

Question:
He says: If I catch up with the imam in the final tashahhud, and a man comes and prays behind me, and I am in a loud prayer, such as Maghrib or 'Isha', for example, do I recite al-Fatihah and the other verses from any surah aloud? Please guide us, may Allah reward you with good.

Answer:
It is not recommended for a masbuq (one who joins the prayer late) to be an imam. So, if a person comes and catches up with the imam while he is praying with the people, he joins him. When the imam concludes the prayer, he stands up and makes up what he missed of the prayer, completing his prayer. And the one who enters should not make this masbuq his imam. Rather, this person who enters does not need for other people to enter and pray with him; or he prays alone if no one comes. If one of the worshippers stands up and prays with him, that is a favor to him, and this is recommended, so it becomes a voluntary prayer for him. The Messenger of Allah (peace and blessings be upon him) said when a man entered and the people had already finished their prayer: ? If one of the worshippers stands up and prays with him, it becomes a congregation, and this is better, so it becomes a voluntary prayer for this worshipper. As for entering and following a masbuq for what he missed of the prayer, this is not recommended; because the ma'mum (one praying behind the imam) does not have an imam during the prayer except in the case of substitution, if the imam appoints him as a substitute. And this person is not a substitute appointed by the imam. Yes. May Allah reward you with good, and may He do you good.
