This point that "how  is God and his attributes" is an important issue in Islamic theology, philosophy of religion, philosophy and mysticism.  According to the philosophical and logical doctrine, allegory or exemplification is not certainly; and could not be used so many in philosophical subjects. But there is many signs in Islamic philosophy that shows they have used allegory unusually in philosophical activity. Such as using suggests a  special philosophical thought path peculiar to them. I want to show that, generally, there is two kind of exemplification in the Islamic source of thought that one is "example = mesl" and other one is exemplar= masal or mesal.  The important phrase of Islamic philosophers especially Mulla sadra saing: God have no example but have exemplar" refers to this distinction. Both part of this phrase refers to two verb of Quran.  Mention to the important exemplar of Islamic philosophy, l believe  that exemplification in example meaning is a lateral resemble and exemplification in exemplar meaning is a resemble in erectile.
