What is the ruling on marrying two sisters and the sister of one's wife?

The questioner : This prohibition is not a temporary prohibition, because what is forbidden is marrying two sisters, not the wife's sister. Notice, the forbidden thing is not the wife's sister, but rather marrying two sisters, as Allah the Mighty and Majestic said. Yes. It differs. It differs. The people we left behind. What is it? It differs. It differs.

The Shaykh : The sister of the sister, the sister of the sister, yes.

The questioner : What? Perhaps Muhammad comes to us regarding her brother, the third one, when her father was married to 'Adi's mother. One of the wives is divorced. One of the wives. And she had children, so she married another man and had children. That man's children are my brothers, my brothers, my father's brothers, and not my father's brothers.

The Shaykh : Is this understood? Is it clear? Who is faster than the one who says it is clear? I see you say it is clear, and then when the exam comes, you say it is clear, come on.

The questioner : Is this not the case?

The Shaykh : Her speech is easier.

The questioner : Draw it.

The Shaykh : Yes, draw it.

The questioner : For example, my father married two women. And among them, meaning my mother, is among them.

The Shaykh : Zayd.

The questioner : Then, meaning, uh, and the second woman, yes, brought a child, for example, a boy, and uh, and my mother brought me, for example, okay, and the second mother was divorced from my father, yes, and married another man, okay, and had a child from him, yes, uh, or a daughter, I will speak about the daughter, correct, she had a daughter, so I mean, that third one, the second daughter, the second daughter becomes the sister of my sister.

The Shaykh : And your sister, your sister? The sister of your sister from the father.

The questioner : If the father.

The Shaykh : Yes, good, correct, so the sister of your sister is sometimes forbidden to you and sometimes lawful, if your sister is from her mother, yes.
The sister of your sister from her mother, and this is your sister from the mother, and she is the sister of her sister from her mother. So it is forbidden, because your two mothers are one. And if your sister is from her father, then it is lawful, because there is no prohibition between you and her. The picture of the issue is a person born from a woman under a husband, born from a woman under a husband, and he has a sister. From his mother, prior to the first husband, prior to his father, meaning this mother who bore him from this husband has a daughter from a previous husband, so she is his sister from where? Who is his sister?
From his mother, this sister from the previous husband has a sister from her father, who is the mother of this child? So she became her sister from her father, is it lawful for her brother from her mother or not? Okay, bring the question.
