Is the Koran scientifically a miracle?
performing miracles is in order to give proof of the authenticity of message of God that it proceeds in fact from the Creator of the universe.
A miracle is an act that cannot be performed by the aid of learning and practice.
please look http://www.quranmiracles.com/ and please read and understand at least few of scientific claims or predictions of Koran in this link according to your scientific specialty.
if Koran is a miracle it is standing challenge for all times and places. In other words, it is alive while other miracles are temporary or dead. Hence, the latter might be questioned or doubted but not Muhammad's miracle.
it is claimed by Muslims that Koran has many scientific predictions and has no conflict with valid science and it is impossible an unread man at age of 40 immediately say such things in Koran in the context of Arabia at 1400 years ago.
is Koran the miracle or our era?
