"The relation of Qada and Qadar (predestination) with the optional actions"

Most of the people have a false understanding of predestination (Qada' and Qadar); for example, when they have a car accident, they attribute it to "kismet" and predestination without thinking about their faults and law violations. Therefore, having a true understanding of Qada' and Qadar may help to avoid such mistakes. "Qada" means the certainty of an event its causes and "Qadar" means the boundaries and characteristics of the event. In fact Qada' and Qadar means provoking of all the causes which stems from will and knowledge of Allah. Among the events in the universe, the human actions are among those that depend on human will an addition to several other causes, i. e. what mankind does with free will is also under Qada' and Qadar. The present paper studies the relationship between Qada' and Qadar and the optional actions of mankind.
