Joining a second congregation for one who is making up a missed prayer

The presenter:
Abu Mish'al, please come on to the line.

The questioner:
Peace be upon you.

The presenter:
Peace be upon you.

The questioner:
How are you, Shaykh? May Allah reward you with good.

The presenter:
May Allah welcome you.

The questioner:
If you would be so kind, I entered the midday prayer after the imam had already started the prayer. Now, listen to me, Shaykh.

The presenter:
Yes.

The questioner:
And I was with the people who had entered the mosque with me. Then another group came and established the prayer in the same place where I was praying. After I finished my prayer, I asked the brother who established the second prayer if it was permissible to establish two Friday prayers. He said that was not correct and that there was no problem with the establishment.

The presenter:
Okay, thank you. Please, Shaykh. Yes. He says that he entered for the Zuhr prayer, Honorable Shaykh, to make up what he had missed, then he prayed, and after that, another congregation was established behind the mosque.

The Shaykh:
Yes, if he stands up after the imam’s taslim to make up what he missed, and latecomers come and pray, he does not join them. He completes his prayer alone and does not join them in the remainder of his prayer. Yes.
