(Q) Non-Muslim: Why does Islam call for believing in the prophets,
messengers, and holy books that they brought as a revelation from
(A) Muslim: From a mental point of view, the human being with
his external qualities and internal systems is like a machine with its
components, but he is more complex than any machine. Suppose
the machine needs an instruction book from its maker and inventor to
explain how to operate it and the method of its optimal use to avoid
damaging it. In that case, this means that it must be recognized that it has
not only a maker but that this manufacturer - although we do not see it -
controls how this machine operates its conditions, and its use through
the instruction book he set for it.
Therefore, if this is the case for a man-made machine, what about
a human being who is more complex than any machine?
Man needs a book of instructions and guidance controlling
his behavior. It is a reason for organizing and evaluating his way of living
according to the controls set by his Creator and Maker (Almighty God)
because He knows him more than himself. His prophets and Messengers are
chosen to deliver His legislation and teachings to them in these books.
