Ibn Sirin narrates the like of it from Ubaydah, that the woman said: The decision is acceptable to me; I am content. The man said: Separation is not acceptable. Ali (may Allah be pleased with him) said: That is not right for you; you will not be able to move from here until you are content just as the woman has expressed her contentment.
