"for example doesn't the zohar say something like that the 3rd temple will drop out the sky onto the mosque ?"
Yea, but these are Midrashim. The truth is that YES what they say WILL happen, BUT the problem is that its not what we think in them happening. These are Midrashim and they are talking in a more higher, spiritual, refined language. For example when they are talking about the third temple descending from heaven it doesn't mean that now forget about the physical part. It is talking about the "Soul" of the Beit Hamikdash, and just we have a body, and a soul (and higher soul, etc.) soo too something Holy like the Beit Hamikdash, soo it is talking about the "Soul" of the Beit Hamikdash again returning, but what is a body without a soul?
