A useful audiobook in English in which its author relies on logic in an interesting manner. The book title is not literally meant but the author wants to relate a fictional story of a man in a few lines. In fact, he wants to say that it is not appropriate for wise people to believe in all the ideas that they face around them without reflecting or thinking to prove their validity or invalidity. Therefore, Allah often praised the people of intellect and called them people of understanding. The goal of this book is to prove the divinity of Allah and his being deserved to be worshiped, based on rational proofs mentioned by the author within this interesting book.
