From Sahih Muslim (Hadith 7553):
Jabir reported that 'Abdullah b. Ubayy b. 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 b. Ubayy b. Salul compelled them). They made a complaint about this to Allah's Messenger (ﷺ) 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
