assalmu 'alaikum -
1. I have read that if you mispronounce Allahu akbar takbir in salat, it invalidates salat, is this true? because it changes the meaning. If so, is it only if you do it intentionally? By mispronounce, I mean lengthen the initial A.
2. I read Hanafis are supposed to stretch out the allahu akbar so it covers the position change(for example going from sajda to sitting position), is this true, or better to say it quickly then change position so there is no mispronounciation?
