Allah is The All Wise, and wisdom implies placing everything in its correct position; there is great wisdom behind everything that Allah has created and legislated, which His slaves may or may not grasp. It is those scholars with deep understanding and firm knowledge who may comprehend some of these wisdoms. Allah did not create anything uselessly or aimlessly. There is wisdom behind everything that appears evil; snakes, scorpions, poverty, diseases, famine, earthquakes, volcanoes, and even the existence of disbelief upon the earth. There is wisdom behind everything, even the creation of Satan, which only the people of knowledge can comprehend.
