Prayer without reciting al fatiha, but didn’t knew that it was obligatory
aasalamu aleykum wa rahmatullahi wa barakatu
If one didn’t know that it’s obligatory to read surah al fatiha, and has many times not read it all, because the iman was going down to ruku, does he have to perform the prayers again. It’s should be noted that I cannot remember how many prayers that was.
Jazakumallah khairan
Answer
Wa’alaykum as-Salām waraḥmatullāhi wa barakātuhu,
Since the times of all those prayers have passed, if he at least recited a little of the Qur’ān in the standing posture, he does not need to repeat any prayer. He should repent.
