Reciting Surat Al-Fatihah in Prayer
If I am a muqtadi (person following the imam in prayer) behind an imam in the silent prayers (Zhuhr and `Asr) and I forget to recite Surat Al-Fatihah (the Opening Surah), what is the ruling of such prayer?
`Ubadah ibn As-Samit narrated that the Prophet (peace be upon him) said, “Whoever does not recite Al-Fatihah in his prayer, his prayer is invalid.” (Al-Bukhari)
Based on this hadith, it is clear that reciting Al-Fatihah is one of the essential parts of the prayer, and is to be recited in each rak`ah both by the imam and the followers.
The scholars have two opinions regarding such ruling:
1- Most scholars are of the view that the imam or the followers must recite Surat Al-Fatihah on their own particularly during the rak`ahs in which the imam recites silently or during the whole silent prayers such as Zhuhr (Noon Prayer) and `Asr (Afternoon Prayer).
2- Imam Abu Hanifah sees that the follower does not have to recite Surat Al-Fatihah during the congregational prayers because the imam recites on his behalf.
