Musannaf Ibn Abi Shaybah 30677 — A woman who marries her slave

Isma'il bin Muslim said: I asked Ata, Abdullah bin Ubayd bin Umayr and Mujahid about a woman who had a slave, and she intended to free him on the condition that he marry her: what is the ruling on this? Ata and Abdullah bin Ubayd said: She should free him and not impose a condition on him. And Mujahid said: In this there is a punishment from Allah and from the ruler: he is to be separated from her and the prescribed punishment (hadd) is to be established on the woman.
