Shaykh Saduq stated...
Shaykh Saduq stated: "Our belief in this respect is what has been taught by Imam Jafar al- Sadiq (the sixth successor/grandson of Prophet): There is no compulsion (by God) and no relinquishing the authority (of God); but a condition between these two conditions. Then Imam was asked: How is it? He said: Suppose you see a man intending to commit a sin; and you forbade him; but he did not listen to you; and you left him; and he did commit that sin.
Now when he did not pay attention to you and you left him, nobody can say that you ordered him or allowed him to sin." Shi'i reference: Shi'ite Creed (al-Itqadat al-Imamiyyah), by Shaykh Saduq In other words, we believe that God has given us power and will and then has left us free to do what we like. At the same time, He has taught us through prophets, what is right and what is wrong. Now, as He is Omniscient, He knows what will be our actions in different times of our life.
But this knowledge does not make Him responsible for our actions more than a meteorologist can be responsible for cyclones and storms, if his forecasts comes true. True forecasts are the result, not the cause of the impending event.
The Sunni scholars on the other hand say that Allah is the Creator of all of our acts: "No act of any individual, even though it is done purely for his benefit is independent of the will of Allah for its existence; and there does not occur in either in physical or extra terrestrial world the wink 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 hurt, success and failure, sin and righteousness, obedience and disobedience, and polytheism or belief." Sunni reference: al-Ghazali (as quoted in Shia of India, p43) PROPHETHOOD Based upon their belief of LUTF (Grace), the Shiats believe that it is incumbent upon Allah to send prophets and their successors in this world to put people on right path. The Sunni scholars say that it is not incumbent upon Allah, because they do not accept necessity of Grace.
SINLESSNESS: The Shiats and Sunnis in first instance, and then the Sunnis among themselves, disagree about the theory of ISMAH (sinlessness; protection) of the prophets. What is our conception of sinlessness? It is the Grace of Allah which helps a person to refrain from sins, without effecting in any way his will and power.
