over time.
Nonetheless, with their own popular hi-tech analogy, Muslims open the door
to a logical follow-up question that is truly heretical in Islam: is there no
possibility, then, of a still later revelation, a Word 9.0? For Muslims,
the Prophet
Muhammad brought the final and perfect revelation that cannot be improved
upon; there will be no more legitimate prophets. Muhammad is thus the “seal of
the Prophets.” This belief has put Islam in the curious position of being quite
tolerant in looking back into religious history, but intolerant in looking forward
to any possible post-Muhammad religious teachings that involve new revelation;
this is the source of the intense strain Islam has with the later Ahmadi, Sikh, or
Baha’i
religions, which have some foundation in Islam but which in effect
“update” Islam in the preaching of still later prophets. These three movements
are thus vigorously condemned by Muslim clerics, and their followers have been
subject to persecution in several Muslim states.
