The denial of causality has very practical consequences in Muslim life. For instance, between 1983 and 1984, weather forecasts were suspended by the Pakistani media. This was because Muslim scholars had complained that the prediction of rain lies outside of what can be lawfully known to man. If God is unpredictable, and He directly causes the weather, how can one forecast it? The attempt to predict the weather is a blasphemous presumption.
Here is a more recent example in the same vein from the Nigerian Islamist group Boko Haram. Its founder Mohammed Yusuf proclaimed that "All knowledge that contradicts Islam is prohibited by the Almighty." Like the weather. Yusuf said, "There are prominent Islamic preachers who have seen and understood that the present Western-style education is mixed with issues that run contrary to our beliefs in Islam. Like rain. We believe it is a creation of God rather than an evaporation caused by the sun that condenses and becomes rain. Like saying the world is a sphere. If it runs contrary to the teachings of Allah, we reject it."
