The Qur’an says...
What God commanded us to do become good by virtue of His command. What he forbade became evil. The Shi’as believe that there is intrinsic good or evil in things. God commanded us to do the good things and forbade the evil. God acts according to a purpose or design. Human reason cannot comprehend this design or purpose in its entirety though man must always strive to understand as much as he can. Compulsion or Freedom? The various schools of thought are divided.
The Sunni scholar Al-Ghazzalli sums up this doctrine as follows: “No act of any individual, even though it be done purely for his benefit, is independent of the will of Allah for its existence. There does not occur in either the physical or the extra-terrestrial world the twinkle of an eye, the hint of a thought, or the most sudden glance except by the Decree of Allah, of His Power, Desire, and Will.
This includes evil and good, benefit and harm, success and failures, sin and righteousness, obedience and disobedience, polytheism and true belief.” • The Shi’as believe that there is neither total compulsion nor total freedom. The true position is the one in-between. They maintain that Allah has fore-knowledge of human action but does not compel man to any particular course of action.
