An-Nur 24:33 وليستعفف الذين لا يجدون نكاحا حتى يغنيهم الله من فضله والذين يبتغون الكتاب مما ملكت ايمانكم فكاتبوهم ان علمتم فيهم خيرا واتوهم من مال الله الذي اتاكم ولا تكرهوا فتياتكم على البغاء ان اردن تحصنا لتبتغوا عرض الحياة الدنيا ومن يكرههن فان الله من بعد اكراههن غفور رحيم ٣٣

And let those who cannot find a match keep chaste till Allah give them independence by His grace. And such of your slaves as seek a writing (of emancipation), write it for them if ye are aware of aught of good in them, and bestow upon them of the wealth of Allah which He hath bestowed upon you. Force not your slave-girls to whoredom that ye may seek enjoyment of the life of the world, if they would preserve their chastity. And if one force them, then (unto them), after their compulsion, lo! Allah will be Forgiving, Merciful.
