The universe, according to Islam, is created and originated by God. He is the sovereign in the universe who both expands and terminates it in his apportioned time. Hence, all the laws (sunan ar.) that pervade the universe are under His hegemony. If He should so will, he may terminate the effect of those laws- though they are invariant and unchanging. Existence is an orderly cosmos and not a chaos. The Qur`an continually enjoins people to reflect on and discover nature and the universe. Although the scientific spirit has receded in the later ages of Islam, it is very positively depicted in the Qur'an; nevertheless, it is a scientific spirit that repudiates paganism and that portrays the world as being a manifestation of Divine sovereignty: To quote from the Qur'an: "May He be glorified, for whatever is in the heavens and the earth is His, all are submissive to Him." (2:116)
