In the debate, Hamza says the following
The traditional western philosophical definition of a miracle as summaried by David Hume in his 'an enquiry concerning human understanding', he says it’s a "transgression of natural law". We don’t agree with that definition. Because what are natural laws? Natural laws are just inductive generalisations of patterns we perceive in the universe. If something changes from the pattern or is different. They maybe its just part of the pattern. Its just based on induction.
What the profound Islamic theologians and thinkers have done, is they’ve redefined what a miracle is based on the quranic discourse. And they have said that a miracle is “an event that lies outside the productive capacity of nature”. Which means, when you go to the nature of the event, you exhaust all possible naturalistic explanations, and also there is no naturalistic causal link between the event, and the nature of the event. This is a far more coherent definition.
Who are these profound Islamic theologians and thinkers who have defined 'miracle' in this manner? Hamza does not mention any names. this is suspicious for a man who names drops as enthusiastically as Tzortzis. Perhaps his website may clarify the issue:
According to philosophers such as William Lane Craig a miracle is defined as “events which lie outside the productive capacity of nature”.
