And whoever among you has not within his power ampleness of means to marry free believing women, then (he may marry) of those whom your right hands possess from among your believing maidens; and Allah knows best your faith: you are (sprung) the one from the other; so marry them with the permission of their masters, and give them their dowries justly, they being chaste, not fornicating, nor receiving paramours; and when they are taken in marriage, then if they are guilty of indecency, they shall suffer half the punishment which is (inflicted) upon free women. This is for him among you who fears falling into evil; and that you abstain is better for you, and Allah is Forgiving, Merciful.

Say to those of the dwellers of the desert who were left behind: You shall soon be invited (to fight) against a people possessing mighty prowess; you will fight against them until they submit; then if you obey, Allah will grant you a good reward; and if you turn back as you turned back before, He will punish you with a painful punishment.
