If while praying a person makes a mistake in Surah Fatiha and realizes his mistake after saying Ameen does he have to begin recitation again from the beginning or should he start from the Ayah that he got wrong? What about a person who makes this mistake behind an imam and has to hurry because the Imam has started bowing?
May Allah forgive me if I am wrong, but I was brought up knowing that the imam is responsible for the recitations while in congregation. You can recite El fatiha and other sura for yourself but this is not obligatory.
If you are performing salah by yourself, then just repeat the whole sura.
At the end of the salah, before you salut the angels on both sides, perform 2 more sajdas for repentance for the mistake.
Assalaamu a'laykum wa ragmatullahie wabarakaatu!
I'm not learned. As far as my to my knowledge, surah faatiga is the only surah you have to recite otherwise your salaah null and void. You are allowed to make 3 mistakes more than that your salaah is null and void.
In congregation: You recite after the Imam. He will be silent before he starts with the short surah and that is for you to recite surah faatiga. If you did not get to complete surah faatigah it's OK because you made niyyah Imaaman liellaahie ta a'lah.
It is no need to make the sujud of forgetfulness for surah faatigah though it is a fard requirement.
Jazaaqallaah min gheir!
Wssalamualaikum wr wb, Allah knows best.
You should repeat from where you made mistake. I am still not sure that, one has to give prostration of forgetfulness or not for mistake in one verse/ anywhere in Al Fatiha, but it is the obligatory part of salah, that's why I personally give prostration of forgetfulness as a repentance. I am still trying to correct my salah.
Allah knows best.
