In Islam, Allah is the ultimate Truth (al-Haqq). He is the Creator and His creation stands for the manifestation of His holy attributes. The creation is also a compendium of signs (ayat) which advances, as well as facilitates, the reading of the world which, in turn, leads to an understanding and appreciation of the Creator.
Knowledge, it follows, is closely related to the truth. It is about knowing the true and actual states of things at any level of the existential reality, be they most magnificent or most inconsequential. What matters is the truth, not the quantifiable dimensions of things. Indeed, knowledge and truth are two faces of the same coin.
