Quran 24:32 — Light (Al-Noor)

You shall encourage those of you who are single to get married. They may marry the righteous among your male and female servants, if they are poor. GOD will enrich them from His grace. GOD is Bounteous, Knower.

[24:31] And tell the believing women to subdue their eyes, and maintain their chastity. They shall not reveal any parts of their bodies, except that which is necessary. They shall cover their chests, and shall not relax this code in the presence of other than their husbands, their fathers, the fathers of their husbands, their sons, the sons of their husbands, their brothers, the sons of their brothers, the sons of their sisters, other women, the male servants or employees whose sexual drive has been nullified, or the children who have not reached puberty. They shall not strike their feet when they walk in order to shake and reveal certain details of their bodies. All of you shall repent to GOD, O you believers, that you may succeed.*

[24:33] Those who cannot afford to get married shall maintain morality until GOD provides for them from His grace. Those among your servants who wish to be freed in order to marry, you shall grant them their wish, once you realize that they are honest. And give them from GOD's money that He has bestowed upon you. You shall not force your girls to commit prostitution, seeking the materials of this world, if they wish to be chaste. If anyone forces them, then GOD, seeing that they are forced, is Forgiver, Merciful.
