Is it permissible to recite a short surah after al-Fatihah when the imam is reciting a short surah?

Question:
Is it permissible to recite a short surah after al-Fatihah when the imam is reciting a short surah, or should we listen to the imam's recitation? May Allah reward you with good.

Answer:
In the name of Allah, the Most Gracious, the Most Merciful. All praise is due to Allah, Lord of the worlds, and may Allah send prayers and blessings upon our Prophet Muhammad, and upon his family and all his Companions. To proceed: If the prayer is one in which the recitation is loud, it is obligatory for the ma'mum (one praying behind the imam) to listen to the imam's recitation and pay attention to it, as stated in This applies to the recitation of the surah after Surat al-Fatihah, and there is no disagreement on this point, as far as I know.
As for the recitation of al-Fatihah, is it obligatory for the ma'mum to recite al-Fatihah? This is a point of disagreement among the scholars. In a prayer with silent recitation, where the imam does not recite aloud, the ma'mum recites; he recites al-Fatihah, and he recites a surah after it, or whatever is easy for him of the Qur'an in the silent prayer. Yes.
