4:25 If any one of you do not have the affluence to be able marry free believing women, (let him marry) from among the believing women that your right hand owns. Allah knows best your belief, you are from each other. Marry them with the permission of their people and give them their wages (dowry) honorably being women in marriage and chaste, not taking lovers. If, after marriage they commit adultery, they shall be liable to half the punishment of a married (free) woman. That is for those of you who fear fornication, but it is better for you to be patient. Allah is the Forgiver, the Most Merciful.
4:26 Allah wishes to make this clear to you and to guide you along the ways of those who have gone before you, and turns towards you. And Allah is the Knower, the Wise.
