What is obligatory for the imam if he remembers during the prayer that he is not in a state of ritual purity?

Question:
May Allah reward you. The program's phone number is displayed by the episode's producer, and please provide us with the contact details. 'Abd al-Rahman from 'Asir, please go ahead, 'Abd al-Rahman. Peace be upon you. And upon you, peace. I have two questions. The first question, my brother, is that I was the imam and I remembered that I was not in a state of ritual purity in the final tashahhud, just seconds before the taslim. I do not know what the ruling is on my prayer and the prayer of the imam and those behind me. Wait a moment, the Shaykh will answer.

Answer:
As for the ma'mum (those praying behind the imam) who did not know about your situation, their prayer is valid. Their prayer is valid. If you did not know until after the taslim, their prayer is valid. As for you, you stand up, perform ritual purity, and repeat the prayer. However, if you remember that you are not in a state of wudu' (ablution) during the prayer, it is obligatory for you to leave; it is obligatory for you to leave and not continue the prayer. You should have someone lead the congregation or wait until you perform ritual purity and come back to pray with them. Yes.
