If the imam forgets the bowing and does not know what he forgot, is it prescribed for the one praying behind him to recite, for example, “And bow with those who bow”?

Question:
He says: Honorable Shaykh, may Allah grant you success, if the imam forgets the bowing (ruku') and the one praying behind him recites a verse to remind him, as in the phrase , is that because the imam does not know what he forgot?

Answer:
The Messenger (peace and blessings be upon him) indicated that one should say the tasbih, but they said that if the imam does not become aware, or does not know what it is, he may be alerted with a suitable verse from the Qur'an, and this is permissible, yes.
