did you not get it...the person is not muslim...just have a muslim name for this account, and through such useless question for some anti islamic sentiment's satisfaction or there might be any agenda behind this...Allah know better..A very brief and just answer.. Though there are many other points to reply to this question..
But i wonder.. What kind of Iman we have that we still dont understand the basics of Islam and we get entangled into such questions which themselves seem so dumb... How can one even think that anyone is praying to this structure we call Bait Ullah..
