The content of this rubric was taken from a movie which shows talks and conferences of known scientist with different scientific background. Topic of the meetings was to discuss the scientific theses which are to be found in the Qur'an. In addition people wanted to prove that Islam supports science and research und that the verses in the Qur'an are not contrary to the results of scientific research so far.
The scientists who took part in the discussions were all Non-Muslims. After years of research und work the presented the audience their latest theses and results. They were amazed to know, that their topics were already addressed to in the Qur'an 1400 years ago. Their comments to this were different, but nearly all of them stated that the Qur'an cannot be of human origin. In fact some of the scientists became convinced of Mohammad as a messenger. One of the scientists became convinced by the truth in such a way that he at once became Muslim and spoke the shahada, the Islamic profession of faith.
The truth of Islam was proved by these people who had no arguments against the verses of the Qur'an. In addition their colleagues and "usual" people ware witnesses of these events. These people open doors for other people by proving the truth and improving the understanding of the secrets of the Qur'an. They smooth the way to the true belief in God, the Lord of the universe.
What excuse can somebody have, who has seen the proofs and statements of the scientists and yet refuses to belief? Allah tells us in the Qur'an:
Those whom Allah (in His plan) willeth to guide, He openeth their breast to Islam; those whom He willeth to leave straying, He maketh their breast close and constricted, as if they had to climb up to the skies: thus doth Allah (heap) the penalty on those who refuse to believe. (6, 125 )
