Law and Morality:

Since morality contain of prescriptions of the society and is not enforceable, hence rules of law are enforceable.  However wrongs in society are contraventions of either morality or law or both.

Moreover law incorporates a significant proportion of morality and to that extent morality is enforceable.

In fact such rules/contraventions are contraventions of law for example murder, rape theft by servant or agent.

Just to in summary therefore, law is an aggregate of conglomeration of rules enforced through courts of law at a given time.

However rules of law originate from acts of parliament and religious practises, customary of the people that they may be borrowed from other countries also.
