وهو تحديد كل مخلوق بحده الذي يوجد من حسن وقبح ونفع وضرر
It is the specifying of each created thing according to its determinate condition, whether good or bad, beneficial or harmful.
Qadar here concerns specification: what a created thing is, the features it possesses, and the consequences accompanying its occurrence. It is not limited to numerical quantity; descriptions of its time, place, condition, and outcome also belong to the discussion.
Determination does not mean that a human act ceases to have a moral agent. The origination and specification of an act are one question, while its status as obedience or disobedience is another.
