It should be reminded that searching and curiosity for recognition of truth is of the dimensions of the human spirit and a part of his/her temperament which intrigues him/her to seek and search. Thus, nobody considers it as his/her innovation.
Besides the holy Quran, the previous religions’ books have invited human being to seek truth; for instance, Ahmad Yazdani, A Baha’ author narrated from the book “Avesta” in the book “the spiritual principles”: O’ the righteous, listen by your own ears and see the nice nature. Then, men and women select their ways for themselves.”
Also, it is written in the Bible: “Search for everything and resort to what is nice. Avoid every kind of wickedness.”
