Does this world have a Creator and God or has it been created by itself without any cause? If there is a God then what are His attributes and works? Does God assign an obligation for us, or are we not without some form of responsibility? Were the messengers truthful in their claims or not? Is it possible that after this world there exists another world whereby a human being would see punishment for his/her deeds? The human faculty of reason, in accordance with his primitive nature and special creation, desires to find out about these realities, remove curtains from these mysteries; provide correct answers for these inquiries and many more alike. The human faculty of reason possesses this distinction in it whereby it can distinguish between truth and falsehood and naturally is inclined to discover the realities and causes of things, and until it rests upon an absolute certainty, it does not feel comfortable.
