Musannaf Ibn Abi Shaybah

Hazrat Abdullah (may Allah be pleased with him) was asked: If a man says that if he marries a woman, she is divorced, and if he buys a slave-girl, she is free, what is the ruling regarding this? He replied: If I were in his place, I would neither marry nor buy any slave-girl.

Hazrat Sha'bi (may Allah have mercy on him) and Ibrahim (may Allah have mercy on him) say that this is nothing.

18804 - From Sufyan, from Mansur, from Ibrahim (they said): If he says: "Eat," (it is) nothing.

It is narrated from Hazrat Zuhri (may Allah have mercy on him) and Hazrat Mak'hool (may Allah have mercy on him) regarding this matter that if a person said, "The woman whom I marry is divorced," they considered this binding.

Hazrat Abdul Malik bin Sulaiman (may Allah have mercy on him) says that I asked Hazrat Saeed bin Jubair (may Allah have mercy on him) that if a person says, "Whichever woman I marry, she is divorced," what is the ruling on this? He replied, "How can you divorce someone whom you do not possess? Divorce only takes place after marriage."
