Quran — Page 82

And [forbidden to you are] all married women other than those whom you rightfully possess [through wedlock]: this is God's ordinance, binding upon you. But lawful to you are all [women] beyond these, for you to seek out, offering them of your possessions, taking them in honest wedlock, and not in fornication. And unto those with whom you desire to enjoy marriage, you shall give the dowers due to them; but you will incur no sin if, after [having agreed upon] this lawful due, you freely agree with one another upon anything [else]: behold, God is indeed all-knowing, wise.

And as for those of you who, owing to cir­cumstances, are not in a position to marry free believing women, [let them marry] believing maidens from among those whom you rightfully possess. And God knows all about your faith; each one of you is an issue of the other. Marry them, then, with their people's leave, and give them their dowers in an equitable manner - they being women who give themselves in honest wedlock, not in fornication, nor as secret love-companions. And when they are married, and thereafter become guilty of immoral conduct, they shall be liable to half the penalty to which free married women are liable. This [permission to marry slave-girls applies] to those of you who fear lest they stumble into evil. But it is for your own good to persevere in patience [and to abstain from such marriages]: and God is much-forgiving, a dispenser of grace.

God wants to make [all this] clear unto you, and to guide you onto the [righteous] ways of life of those who preceded you, and to turn unto you in His mercy: for God is all-knowing, wise.
