Is there a supplication in the Sunnah from the Messenger (peace and blessings be upon him) after the completion of the iqamah for prayer?

Question:
The imam after the Friday prayer informed us and said: When the mu'adhdhin completes the iqamah, none of you should supplicate with any supplication that has not been transmitted from the Messenger of Allah (peace and blessings be upon him), nor has it been transmitted in the Book or the Sunnah. And when the mu'adhdhin mentions Allah in the iqamah, you should mention Allah and remain silent until the imam says takbir. Today, the congregation is occupied with the imam's speech; we hope for your quick response so that we may be reassured.

Answer:
What this imam said is correct, for there is no specific supplication transmitted from the Prophet (peace and blessings be upon him) , nor a supplication to be regularly recited; this has not been transmitted from the Prophet (peace and blessings be upon him). However, if one follows the mu'adhdhin and says what he says, this falls under the saying of the Prophet (peace and blessings be upon him) , because the iqamah is an adhan, because the iqamah is an adhan. So the listener repeats what the mu'adhdhin says when he establishes the prayer, and he receives the reward that the Prophet (peace and blessings be upon him) mentioned regarding following the mu'adhdhin. Yes.
