Allah's saying:
[وَلاَ تُكْرِهُواْ
فَتَيَـتِكُمْ عَلَى الْبِغَآءِ]
(And force not your slave-girls to prostitution...) Among the people of the
Jahiliyyah, there were some who, if he had a slave-girl, he would send her out
to commit Zina and would charge money for that, which he would take from her
every time. When Islam came, Allah forbade the believers to do that. The reason
why this Ayah was revealed, according to the reports of a number of earlier and
later scholars of Tafsir, had to do with `Abdullah bin Ubayy bin Salul. He had
slave-girls whom he used to force into prostitution so that he could take their
earnings and because he wanted them to have children which would enhance his
status, or so he claimed.
