Is the takbir on the two festivals done collectively and with one voice, and if this is done, is it an innovation?

The questioner : Regarding the takbir on the days of the two festivals and likewise the days of Tashriq, no two people differ on the recommended practice (sunnah) of it. But we ask the honorable Shaykh to clarify for us whether this takbir is done collectively and with one voice? And if we do that, is it an innovation?

The Shaykh : The correct view is that it is not done with one voice, but rather each person says the takbir for himself, as Anas ibn Malik (may Allah be pleased with him) said: . So each person says the takbir himself according to the intonation he desires. As for gathering to say the takbir with one voice, I do not know it in the Sunnah.
