Dear brother jawaid,
It is encouraging to see an inquisitive and open mind. We must never be afraid of where the Quranic evidence takes us, even if it goes against our long held views. I did not have time to scrutinise in detail but here are some issues:
1) You seem to imply 2:142 refers to the Jews, despite the following verses demonstrating to the contrary. It most likely refers to the believers, and the Quranic text strongly implies there was a change of qiblah/focus.
2) You seem to have equated "qiblah" with "deen", but this cannot be the case if one thinks there was a change, so I guess this will depend on your answer to (1).
3) There is no facing "kaabah" anywhere in Quran, physically or otherwise.
4) to my knowledge no building is described in Quran as a guidance or truth from our Lord, or given special status etc.
5) the understanding of "sacred masjid" might not fit in several verses I think. Some of them are discussed in that article.
The above are some of the issues. As I mentioned previously, it seems the view of each side requires interpretation and interpolation to support their argument. This is fine to a degree, but it will depend to what degree one finds this acceptable.
