Forbidden to you also are married women, except those who are in your hands as slaves: This is the law of God for you. And it is allowed you, beside this, to seek out wives by means of your wealth, with modest conduct, and without fornication. And give those with whom ye have cohabited their dowry. This is the law. But it shall be no crime in you to make agreements over and above the law. Verily, God is Knowing, Wise!
