In the Quranic thought system, thought cannot be separated from action. The great God, immediately after expressing a truth based on nature-based reasoning and its acceptance by man, asks him to act correctly and sincerely. Look at these enlightening verses: (ذلکم الله ربکم فاعبدوه) (Yunus:۳)  (فالهکم الله واحد، فله اسلموا) (Haj:۳۴) (و اشکر و الله ان کنتم ایاه تعبدون) (Baqareh:۱۷۲) (قد جاءکم الرسول بالحق من ربکم، فامنوا خیرا لکم) (Insan:۳۰) This short speech does not aim at dealing with the roots, causes and consequences of separating science from practice. The purpose of expressing this point was to point to that Qur'anic principle that has been neglected and has made us far away from the accepted model of religion.
