Surah 4. An-Nisaa'

Allah said, those who do not have,

(the means), financial capability,

(Wherewith to wed free believing women) meaning, free faithful, chaste women.

(They may wed believing girls from among those whom your right hands possess,) meaning, they are allowed to wed believing slave girls owned by the believers.

(and Allah has full knowledge about your faith; you are one from another.) Allah knows the true reality and secrets of all things, but you people know only the apparent things. Allah then said,

(Wed them with the permission of their own folk) indicating that the owner is responsible for the slave girl, and consequently, she cannot marry without his permission. The owner is also responsible for his male slave and they cannot wed without his permission. A Hadith states,

(Any male slave who marries without permission from his master, is a fornicator.) When the owner of the female slave is a female, those who are allowed to give away the free woman in marriage, with her permission, become responsible for giving away her female slave in marriage, as well. A Hadith states that

(The woman does not give away another woman, or herself in marriage, for only the adulteress gives herself away in marriage.) Allah's statement,

(And give them their due in a good manner;) meaning, pay them their dowry with a good heart, and do not keep any of it, belittling the matter due to the fact that they are owned slaves. Allah's statement,

(they should be chaste) means, they are honorable women who do not commit adultery, and this is why Allah said,

(not fornicators) referring to dishonorable women, who do not refrain from illicit sexual relations with those who ask. Ibn `Abbas said that the fornicating women are the whores, who do not object to having relations with whomever seeks it, while,

(nor promiscuous. ) refers to taking boyfriends. Similar was said by Abu Hurayrah, Mujahid, Ash-Sha`bi, Ad-Dahhak, `Ata' Al-Khurasani, Yahya bin Abi Kathir, Muqatil bin Hayyan and As-Suddi.

Allah said,

(And after they have been taken in wedlock, if they commit Fahishah, their punishment is half of that for free (unmarried) women.) this is about the slave women who got married, as indicated by the Ayah;

(And whoever of you have not the means wherewith to wed free believing women, they may wed believing girls from among those whom your right hands possess,) Therefore, since the honorable Ayah is about believing slave girls, then,

(And after they have been taken in wedlock,) refers to when they (believing slave girls) get married, as Ibn `Abbas and others have said. Allah's statement,

(their punishment is half of that for free (unmarried) women.) indicates that the type of punishment prescribed here is the one that can be reduced to half, lashes in this case, not stoning to death, and Allah knows best. Allah's statement,

(This is for him among you who is afraid of being harmed in his religion or in his body;) indicates that marrying slave girls, providing one satisfies the required conditions, is for those who fear for their chastity and find it hard to be patient and refrain from sex. In this difficult circumstance, one is allowed to marry a slave girl. However, it is better to refrain from marrying slave girls and to observe patience, for otherwise, the offspring will become slaves to the girl's master. Allah said,

(but it is better for you that you practice self-restraint, and Allah is Oft-Forgiving, Most Merciful.)
