Mispronouncing a word in Salaat
Does mispronouncing a word or omitting a word in anything in Salaat, invalidate the Salaat?
It all depends on the effects produced by the miss pronunciation or omission. If the meaning changes completely or an opposite meaning results, the Salaat will become invalid.
Allah knows best
