What is said after the tashahhud before the taslim

The questioner:
All right, Muhammad, give us the second question, please.

Another questioner:
Regarding the recitation in some of the tashahhuds in the second rak'ah, where we sit, and in the final tashahhud when the imam finishes and we finish the tashahhud, what do we say after that? And there is also a question about the worshippers: when the imam raises his head from the ruku', the people around him hear a loud, high-pitched voice saying, "Our Lord, to You belongs all praise and gratitude, our Lord," and then he talks a lot.

The questioner:
All right, thank you. May Allah keep you safe.

Another questioner:
Thank you.

The questioner:
Yes, his second question, Shaykh, he says: When we finish the prayer, after the tashahhud, what do we say? When the tashahhud ends before the imam says the taslim? Yes, Shaykh Salih?

The Shaykh:
Let him turn off the radio; there is some feedback.

The questioner:
Yes, that is enough. Turn off the radio, Muhammad, or rather, we are finished; we have taken the questions. Thank you, Muhammad. Yes, he says: After the tashahhud, there may be a pause before the taslim; what do we say after the tashahhud? Yes, he says: In the first tashahhud and the second tashahhud, what do we say after the end of the tashahhud? Is there a du'a'?

The Shaykh:
You say the taslim when you finish the first tashahhud and the final tashahhud.

The questioner:
But if you are a ma'mum.

The Shaykh:
If you are a ma'mum, you supplicate to Allah with whatever is easy for you. Yes.
