Q: I used to pronounce the words of prayers in the way I had learned from my parents and in secondary school. After a while, I found out that I had been pronouncing some words in a wrong manner. Is it obligatory for me — according to the fatwā of Imam Khomeini (q.) — to repeat the prayers? Or are all prayers that I performed in that way correct?
A: In the mentioned case, all your previous prayers are correct and you do not have to repeat or make them up in qaḍā’.
