Is it considered a Bid‘ah (innovation in religion) for some women to say "Takbeer" (Allahu Akbar), "Tahmeed" (Alhamdulillah), and "Sallu ala Rasulillah" (invoke blessings upon the Messenger of Allah) while the female preacher is delivering her lecture in remembrance gatherings, and for the attendees to respond with praise, Takbeer, and invoking blessings upon the Messenger of Allah?

The encouragement by a preacher or lecturer for the audience to say "Allahu Akbar" (Takbir) has no basis in the Sunnah (definition). However, there is no harm in it if it is not done continuously, given the general proofs that encourage obedience. But continuous practice could lead to the belief that it is a Sunnah. As for the audience saying "Allahu Akbar" when they hear something that impresses them, this has a basis in the Sunnah, such as in the hadith (definition) of Ibn Mas'ud, when the Prophet, peace and blessings be upon him, said: "Are you not pleased that you are a quarter of the people of Paradise?" He (Ibn Mas'ud) said: "So we said, 'Allahu Akbar'." And glorifying Allah (Tasbih) is prescribed upon seeing or hearing something astonishing.
