Jabir reported that 'Abdullah bin Ubayy bin Salul had two slave-girls; one was called Musaika and the other one was called Umaima and he compelled them to prostitution (for which 'Abdullah bin Ubayy bin Salul compelled them). They made a complaint about this to Allah's Messenger ( صلی اللہ علیہ وسلم ) and it was upon this that this verse was revealed: "And compel not your slave-girls to prostitute" up to the words: "Allah is Forgiving, Merciful."
