Is Islam Was or Was Not....

Re: Why Allah chose Mecca for Last prophet.

yes i can, Judaism is not the religion taught by the Prophet (s) of Banu Ishaaq (AS), the Judaism present in those days ( still in these days) has been highly compromised and have little to do with the reality the Prophet(s) preached to the people on Israel.

Yes i agree, the teaching of Islam is not that different from the teaching of Those Prophet(s), same like Zr-Tasht, taught almost the same and Luqman, the wise, have said many things repeated in Quran and in east, Budha have taught the same.. All the Prophet(s) have taught the same… but at the time of Prophet Muhammad (SAAW) none of the teaching was in practice… that was one of the reasons He (SAAW) was sent…

The earlier Prophet (AS) were sent to revive the teaching or to aid the existing Prophet, not to mention their areas was select group of people/region… the books revealed to those Prophets suggests the same…

Where as Quran have totally over-written everything… Windows example is not valid because, in different circumstances, Windows 2000 would work better than Windows XP whereas, Quran says, all the religion prior to Quran has been abolished and their followers are no longer on right path… ( well to begin with the so-called followers have selected the wrong path)
