Please read my article about (Al Hajj: A Known months ), it may explain to you how the Holly Sacred Mosque is so important in Islam before and after Abraham. It is a bad habit that people usually worship the building of (Al Qa'aba ) itself and make a lot of idols , to worship them beside Allah. This happened before and after the Prophet Mohammed, and we still have it now.
There was not prophet before Mohammad in the Arabs during 8 centuries, while there were a lot of prophets in Israeli 12 tribes, since their grand father Jacob.
This is an Quranic and historic fact.
