A Fortiori Logic in Quran

A fortiori logic is a kind of formal logic which its arguments, unlike the common arguments of Aristotelian logic, has four terms through which after comparing usually two persons, things, works to each other, the description of one of them is ascribed/ denied to/ from the other. This logic, in spite of Sion’s belief, is found in Quran, so richly that we can say that it is the prominent logic of Quran. In this research, I will study a fortiori logic in Quran, after giving an introductory explanation of it.
