Musannaf Ibn Abi Shayba 9:951

'Abd al-A'la narrated to us, from Dawud, from 'Abd Allah ibn Qays, that a servant of Abu Musa—who was the caretaker of his camels—married a slave woman belonging to the Banu Ja'dah and drove five camels to her [as a dowry]. Abu Musa was informed of this, so he sent to them, "Send my servant and my wealth to me." They said, "As for the servant, he is your servant, but as for the wealth, he has made the private parts of our companion lawful with it." They disputed before 'Uthman ibn 'Affan. 'Uthman judged for them [to keep] two-fifths of what he had made the private parts of their companion lawful with, and he returned three-fifths to Abu Musa.
