Question on Salat

My uncle just returned from Mecca and noticed something that has me confused. He said that during Namaz at Kaaba, the Imam never recited “Bismillah” (spelling?) before reciting any surahs throughout the prayers. Is there a reason for this or he may have uttered the words but it was never picked up by the microphones?

Re: Question on Salat

He probably said it under his breath. Just like the begining of Namaz.

Re: Question on Salat

Some sects of Muslims say Bismillah , some do not say it.
Just two examples.
