Imaam who's pronounciation is incorrect
Q: Is prayer valid behind a imaam who pronounces the letter TA as a D and the letter KAF as a G (the farsi GAF)? For example he recites "...ihdinas siraDal musteGim siraDallezine..."
Also on the soft sounded letters he reads the dammah as a german ü i.e. ue and not like u in umar. Also the letter DHAD he reads it sounding to Z.
