The ruling on a latecomer who is appointed as the imam

Question:
A message was received for the program from one of the listening brothers, in which he says: I am a latecomer in the congregational prayer, missing one unit of prayer, and the imam experienced a state of ritual impurity, so I took his place to complete the prayer. What should I do, given that I am a latecomer? I asked one of the people, and he said: You should signal to the people to remain in their position so that you can complete what you missed, and then you all say the closing salam together. Is what he said correct?

Answer:
They do not follow you in the additional units. If you fear that they might stand up, you signal to them to remain until you complete what is required of you, then you say the closing salam and they say it with you, and praise be to Allah.

The presenter: May Allah reward you with good. We will repeat the answer once more. May Allah reward you.

The Shaykh: It is obligatory for you, if you have become the one who succeeded him, to complete your prayer, and they are waiting for you. When you have completed your prayer, you say the closing salam, and they say it with you. If you fear that they might stand up, you signal to them with your hand so that they remain and do not stand up with you. Yes.

The presenter: May Allah reward you, and may Allah reward you with good.
