قضا و قدر refers to the Islamic concepts of divine decree and predestination. In this belief, قضا represents God's will and decisions regarding the universe, while قدر signifies the predetermined fate of individuals. Muslims believe that everything happens according to God's plan, and that He has knowledge of all events, past, present, and future. These concepts are essential in understanding the relationship between free will and divine control in Islam. While individuals have the ability to make choices, قضا و قدر suggests that ultimately, God's wisdom governs the outcomes of those choices. This belief encourages acceptance of life's challenges as part of a greater divine plan.
