The threshold signifies a woman. It was narrated that Ibraaheem (May Allah be please with him) said to the wife of Ismaa’eel (May Allah be please with him): Tell your husband he should change the threshold of his door. She told him that and he said to her: My father has told me to divorce you.
It was said that the threshold refers to the state. A woman said to Ibn Sireen: I dreamt that the lintel of my door fell onto the threshold, and Isaw the two door jambs fall, one outside the house and the other inside.
He said: Do you have a husband and son who were absent? She said:Yes. He said: As for the falling of the lintel, your husband will come soon, but the falling of the jamb outside the house indicates that your son will marry a woman who is a stranger. And that is what happened.
