Certainty in rational sciences and holy Qoran

It has become current in print media and intellectual circle to say that certainty and certainty-based knowledge is the very dogmatism and therefore, irrational; while, in an opposite side, skepticism should be regarded reasonable and logically accepted. In this paper, the first part of the claim has been argued against. For the purpose, etymology, definition and position of certainty in intellectual sciences (logic, epistemology and philosophy) and holy Qoran and traditions have been studied. In addition, availability of certainty, its being valuable for transcendent believes, its state of being analogical and hierarchical, scarcity of ultra-certainty and intuitive grades and its psychological effects have been explained.
