Insight of a Muslim Judge

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!!
