Is the resting sitting performed collectively?

The questioner : It is prescribed that the resting sitting be performed collectively, such that the imam sits and says takbir, and the ma'mum sit because they understand this, and then they stand up together? Is it prescribed for the resting sitting to be performed collectively?

The Shaykh : Hmm, what are you saying, is it prescribed (yusharra') or is it prescribed (yashra')?
The student : It is not prescribed to be performed collectively.

The Shaykh : Strange, what do you mean by collectively? If the imam does it and the congregation does not, is he required not to do it, or is the congregation required to do it?
The student : They stand up as if they were one man; he stands up and they also stand up because they understand this. After he says takbir, he sits as usual and they sit with him, then he stands up and they follow him. As for what we do, the imam does it alone, then each of us stands up individually and sits for it, then stands up a second time.

The Shaykh : Are you asking a question to learn the answer, or how?
The student: Yes.

The Shaykh : I mean, you do not know this ruling.
The student: No.

The Shaykh : Strange, how many times have we said: , and how many times have we given examples, including placing the hands on the chest, including the resting sitting, including raising the hands when moving, and so on? All of this means you still do not know the ruling regarding this question you are asking. If your imam sits for the resting sitting, it is obligatory for you to do so for two reasons: first, because it is a sunnah, and second, because he is your imam. And if he does not perform this sunnah because he considers it not to be a sunnah, then you follow him. But if he considers it a sunnah but follows his desire or considers the people, then you oppose him and follow the sunnah. Perhaps you have received the answer to your question?
The student : My question, O our Shaykh, is about the scenario I see.

The Shaykh : I am telling you, have you received your answer or not?
The student : Yes, yes.

The Shaykh : So what is left?
The student : The scenario I am asking about is that the imam stands up from the second prostration and sits alone, then says takbir. He sits for the rest before saying takbir. He stands up without takbir, sits for the resting sitting, then stands up to the upright position and says takbir. We follow him after we hear the takbir, we come and sit for this sitting and stand up. So my question is: he stands up without takbir from the prostration and sits, then stands up. Is the correct form for the imam to say takbir and sit, or to stand up and sit for the resting sitting alone, then stand up?

The Shaykh : Did you mention takbir at the beginning?
The student : No, I did not mention it.

The Shaykh : Yes, may Allah guide you, you want to repeat the question three times.
The student : Excuse me.
