Q: If in “Ihdeenas-Siratal-Mustaqeem”, I recited dee with a daad mistakenly instead of daal does this invalidate the namaz? I don’t know for sure if I done it, but it seems likely so should I repeat the namaz or is it an acceptable mistake? I didn’t repeat it afterwards.
A: No. This does not invalidate the salaah.
And Allah Ta’ala (الله تعالى) knows best.
