Professor Tejatat Tejasen is the Chairman of the Department of Anatomy at Chiang Mai University, Chiang Mai, Thailand. Previously, he was the Dean of the Faculty of Medicine at the same university. During the Eighth Saudi Medical Conference in Riyadh, Saudi Arabia, Professor Tejasen stood up and said:
“During the last three years, I became interested in the Quran.... From my study and what I have learned from this conference, I believe that everything that has been recorded in the Quran fourteen hundred years ago must be the truth, that can be proved by the scientific means. Since the Prophet Muhammad could neither read nor write, Muhammad must be a messenger who relayed this truth, which was revealed to him as an enlightenment by the one who is eligible [as the] creator. This creator must be God. Therefore, I think this is the time to say La ilaha illa Allah, there is no god to worship except Allah (God), Muhammadur rasoolu Allah, Muhammad is Messenger (Prophet) of Allah (God). Lastly, I must congratulate for the excellent and highly successful arrangement for this conference.... I have gained not only from the scientific point of view and religious point of view but also the great chance of meeting many well-known scientists and making many new friends among the participants. The most precious thing of all that I have gained by coming to this place is La ilaha illa Allah, Muhammadur rasoolu Allah, and to have become a Muslim.”
