Musannaf Ibn Abi Shaybah

Hazrat Ismail bin Muslim narrates that I asked Hazrat Ata, Hazrat Abdullah bin Ubaid bin Umair, and Hazrat Mujahid regarding a woman who had a slave, and that woman intended to free him on the condition that he marries her. What is the ruling on this? Hazrat Ata and Hazrat Abdullah bin Ubaid said: The woman should free him and not impose any condition. And Hazrat Mujahid said: In this there will be the punishment of Allah and the ruler: he will be separated from her and the prescribed punishment (hadd) will be established upon the woman.
