The role of the mind

A man came to Iyas Ibn Mu’awiyah, a Muslim judge famous for his wisdom, and the following conversation took place between them:

Man: What is the Islamic ruling regarding wine?
Judge: It is Haram (Forbidden).

Man: How about water?
Judge: It is Halal (Permissible).

Man: How about dates and grapes?
Judge: They are Halal.

Man: Why is it that all these ingredients are Halal, and yet when you combine them, they become Haram?
The Judge looked at the man and said: If I hit you with this handful of dirt, do you think it would hurt you?

Man: It would not.
Judge: How about if I hit you with this handful of straw?

Man: It would not hurt me.
Judge: How about a handful of water?

Man: It surely would not hurt me.
Judge: How about if I mix them, and let them dry to become a brick, and then hit you with it, would it hurt you?

Man: It would hurt me and might even kill me!
Judge: The same reasoning applies to what you asked me!!
