Is there any [consequence] for someone who says "Allahu Akbar" (God is the Greatest) instead of "Sami'allahu liman hamidah" (Allah hears those who praise Him) when rising from Rukoo' (bowing)?

The statement of the Imam and the person praying alone, "Allah hears those who praise Him" (Sami'a Allahu liman hamidah), is one of the obligatory acts of prayer. If someone forgets it or says "Allahu Akbar" instead and remembers during their prayer, they should perform two prostrations of forgetfulness (sujud as-sahw) before the tasleem. The rule is that whoever forgets an obligatory act or recites a prescribed statement in the wrong place should perform the prostrations of forgetfulness.
