What is required of one who arrives at the mosque and has missed the congregational prayer

Question:
I would like to know the Islamic ruling on a person who comes to the mosque to pray with the congregation, but when he arrives, he finds that the congregation has already finished. What is the ruling in that case? Does he pray alone? Or does he and whoever he finds in the mosque form another congregation? Please give us a ruling. May Allah bless you.

Answer:
If a person arrives at the mosque and the people have already prayed, and it is easy for him to find people to pray with, then he prays a second congregation. This is what is prescribed. He prays a second congregation. It is established that a man entered after the people had prayed, and the Prophet (peace and blessings be upon him) said, "Whoever would give charity to someone, let him pray with him." And in the hadith: So, what is prescribed for one who enters and the people have already prayed is to seek someone to pray with. If he finds someone, that is fine; otherwise, it is prescribed for those present that some of them stand up and pray with him so that he achieves the congregation, based on the aforementioned hadith.
As for the statement of some scholars that he should pray alone and return to his house, this is a weak and weaker position. The correct view is that he prays in congregation with whoever is available. Even if some of the congregation who have already prayed stand up and pray a voluntary prayer with him, that is better, as the Prophet (peace and blessings be upon him) commanded and guided to it. So, whoever would give charity to this person, let him pray with him. Yes. May Allah reward you with good.
