If one forgets to recite al-Fatihah, should he perform a rak'ah and prostrate for forgetfulness?

Q: If the one praying forgets al-Fatihah, should he perform another rak'ah to take its place? And should he prostrate for forgetfulness?

A: If he is a ma'mum, he owes nothing, and the imam bears it for him if he was forgetful, ignorant, or missed the standing. However, if he is the imam or praying alone, he must perform a rak'ah in place of the rak'ah in which he left out al-Fatihah, and he must prostrate for forgetfulness.
As for the ma'mum, he follows his imam. If he forgot, was ignorant, or missed the standing, what he caught up with the imam suffices for him, as mentioned previously; due to the hadith of Abu Bakrah al-Thaqafi (may Allah be pleased with him) that he arrived while the Messenger (peace and blessings be upon him) was bowing, so he bowed without joining the row, then entered the row. When the Prophet (peace and blessings be upon him) said the closing salam, he said to him: , and he did not order him to make up the rak'ah whose standing he did not catch.
