Hypercalvinism practically denies that God accomplishes His decreed ends via ordained means (Faith normatively comes by hearing the gospel, for example). “If God has decreed it, it will happen. I don't need to do anything”. That's more like the fatalistic Islamic concept surrounding Inshallah.
Discussion
You are correct. Hypercalvinism is a form of Calvinism that takes the doctrine of predestination to an extreme. Hypercalvinists believe that God has predetermined everything that will happen, including our salvation. They argue that this means that there is nothing we can do to affect our eternal fate.
This view is often criticized for being fatalistic. It can lead people to believe that there is no point in trying to do good or to follow God, because everything is already predetermined.
However, it is important to note that not all Calvinists are hypercalvinists. Most Calvinists believe that God has predetermined our salvation, but that we still have the ability to choose to follow him. They believe that God uses our free will to accomplish his purposes.
The Islamic concept of Inshallah is also fatalistic. It means "God willing" and is used to express the belief that everything happens according to God's will. This can lead people to believe that there is no point in planning or taking action, because everything is already predetermined.
However, it is important to note that not all Muslims are fatalists. Many Muslims believe that we have the ability to make choices and that our actions can affect our destiny.
Ultimately, whether or not we believe in predestination is a matter of personal faith. There is no right or wrong answer. However, it is important to be aware of the potential dangers of fatalism, whether it is expressed in a Christian or Islamic context.
