@emily at first i just wanna state out (PBUH*) and not only sex slaves but child sex slaves, to anybody that has read the quran you will find it pretty usual as it is still practiced today. Islamic law (Sharia), Ma malakat aymanukum is the term for slaves or captives of war. The purchase of female slaves for sex was lawful from the perspective of Islamic law, and this was the most common motive for the purchase of slaves throughout Islamic history.
Al-Muminun 6 and Al-Maarij 30 both, in identical wording, draw a distinction between spouses and "those whom one's right hands possess", saying " أَزْوَاجِهِمْ أَوْ مَا مَلَكَتْ أَيْمَانُهُمْ" (literally, "their spouses or what their right hands possess"), while clarifying that sexual intercourse with either is permissible. Sayyid Abul Ala Maududi explains that "two categories of women have been excluded from the general command of guarding the private parts: (a) wives, (b) women who are legally in one's possession".
A Muslim slaveholder was entitled by law to the sexual enjoyment of his slave women. While free women might own male slaves, they had no such right.[53] The property of a slave was owned by his or her master unless a contract of freedom of the slave had been entered into, which allowed the slave to earn money to purchase his or her freedom and similarly to pay bride wealth. The marriage of slaves required the consent of the owner. Under the Hanafi and Shafi'i schools of jurisprudence male slaves could marry two wives, but the Maliki permitted them to marry four wives like the free men.
SAHIH AL-BUKHARI
Narrated Aisha:
The Prophet engaged me when I was a girl of six (years). We went to Medina and stayed at the home of Bani-al-Harith bin Khazraj. Then I got ill and my hair fell down. Later on my hair grew (again) and my mother, Um Ruman, came to me while I was playing in a swing with some of my girl friends. She called me, and I went to her, not knowing what she wanted to do to me. She caught me by the hand and made me stand at the door of the house. I was breathless then, and when my breathing became all right, she took some water and rubbed my face and head with it. Then she took me into the house. There in the house I saw some Ansari women who said, "Best wishes and Allah's Blessing and a good luck." Then she entrusted me to them and they prepared me (for the marriage). Unexpectedly Allah's Apostle came to me in the forenoon and my mother handed me over to him, and at that time I was a girl of nine years of age. (Sahih Al-Bukhari, Volume 5, Book 58, Number 234)
Narrated 'Aisha:
that the Prophet married her when she was six years old and he consummated his marriage when she was nine years old, and then she remained with him for nine years (i.e., till his death). (Sahih Al-Bukhari, Volume 7, Book 62, Number 64
Narrated Aisha, Ummul Mu'minin:
The Prophet (peace_be_upon_him) used to kiss her and suck her tongue when he was fasting. (Sunan Abu Dawud, Book 13, Number 2380)
Fatwah 23672:
The inquirer asks: "My parents married me to a young girl who hasn't yet reached puberty. How can I enjoy her sexually?"
The imam answers him by saying: "Do not harm her if she cannot take intercourse but you may hug her, kiss her, and ejaculate between her legs"
