I hope someone that is knowledgeable (maybe a talib-ul-'ilm) or knows someone knowledgeable could answer this question for me.
I recently found out that you utter the takbir after the second sujud as you get up from it. Til' now, I've always uttered the takbir after I've come up from the sujud and already stood up. That is, I get up from the sujud, stand up, utter the takbir and start reciting al-fatiha, when the right way to do it is to say "Allahu akbar" as you lift your head from sujud.
Does this invalidate my prayers? Do I have to repeat them?
I hope someone can answer. JazzakumAllah khayran.
