Musannaf Ibn Abi Shaybah

Hazrat Ubaidullah bin Umar (may Allah have mercy on him) narrates that I asked Hazrat Qasim (may Allah have mercy on him) about a man who said that the day I marry such-and-such woman, she is divorced. What is the ruling regarding this? He replied that when he marries her, she will be divorced. Hazrat Umar (may Allah be pleased with him) was asked that if a man says about a woman that the day I marry such-and-such woman, on that day she is to me like the back of my mother, what is the ruling regarding this? He replied that he cannot marry her until he gives the expiation.
