What is the ruling on the ma'mum saying after the end of the iqamah: "May Allah establish it and make it permanent," or reciting the words of Allah the Exalted?

The questioner : He says: Your Eminence, some of the brothers among the worshippers say after the mu'adhdhin finishes the iqamah, either "May Allah establish it and make it permanent as long as the heavens and the earth remain," or they recite the words of Allah the Exalted regarding Ibrahim: What is your opinion regarding this supplication in this specific context? I mean reciting the verse. Is it to be denounced upon the person, even though he is supplicating with it? And did a supplication after the iqamah come from the Prophet (peace and blessings be upon him)? I ask for clarification. May Allah reward you.

The Shaykh : There is no supplication after the iqamah. Rather, it is prescribed for the imam to begin the prayer after the iqamah ends and after he straightens the rows himself or through his deputy. This is because the Prophet (peace and blessings be upon him and his family) would not be able to begin the prayer by saying takbir until the rows were straight. He (peace and blessings be upon him) would even walk through the rows from the beginning to the end, straightening them by the shoulders and chests, saying: When the people increased in the time of 'Umar and 'Uthman, the caliph would appoint men to walk through the rows and inspect them after the iqamah. When they came and said that the rows were as they should be, they would begin the prayer. There is no supplication after it, meaning after the iqamah.
As for saying "May Allah establish it and make it permanent as long as the heavens and the earth remain," the phrase "as long as the heavens and the earth remain" did not come from the Prophet (peace and blessings be upon him).
As for saying "May Allah establish it and make it permanent," this is said when "The prayer has been established" is recited, because there is a weak hadith regarding it. This weak hadith is not acted upon by a group of scholars. Therefore, "May Allah establish it and make it permanent" is not said, neither after the recitation of "The prayer has been established" nor after the completion of the iqamah.
As for the supplication of Ibrahim: This also has no basis whatsoever, and supplicating with it did not come from the Salaf. Therefore, leaving it is better and more desirable. Yes.
