Is extending the takbir considered a bid'ah (religious innovation)?

The questioner : Some people argue that it is a bid'ah (religious innovation) because the Arabs did not extend it in this place, as it is not a place of continuous speech. They say that if you extend it, we are certain that you have innovated, because the Prophet was an Arab and did not know...

The Shaykh : In any case, other people will come to you after this saying, "This is a new religion. We found all the scholars before you praising it." And if one follows the way of the common people, what will bring you to the call? But I say, by Allah, it means that if the truth is made clear to the common people and a group , then if the Messenger of Allah did this, on what basis are you proving it to us? And it is incumbent upon us to say it from the first prayer we perform after it is established with Allah. At that point, they will be silent, because when the truth is made clear to the common person, it becomes evident. Yes.

The questioner : Al-Nawawi mentioned that the Messenger of Allah (peace and blessings be upon him) used to extend the takbir during the pause for rest.

The Shaykh : From al-Hijaz, al-Nawawi, how far is he from the Messenger of Allah (peace and blessings be upon him)?

The questioner : Give me the evidence exclusively.

The Shaykh : I am asking you, how far is he from the Messenger? Is the chain of narration broken or connected? Of course, let him prove this with a chain of narration to the Messenger of Allah (peace and blessings be upon him). May Allah reward you with good. Show us this.
