You are the only thing that is "highly laughable" here, since you just don't know when to quit.  Dividing the slaves up and casting lots to see who gets them is the same as selling/barter. They are a commodity in this example.  Selling does not mean money changes hands, especially when you don't live in a cash economy.  Are you going to now tell us you can find 100 examples in the ahadeeth to say Mohammed only dealt in credit cards now?
