Machine translationRead the Arabic original
The questioner:
A man says: I have two wives. From the first wife, I have a daughter, and my son has a child.
The Shaykh:
My son has a child, meaning he has a daughter and a son.
The questioner:
Yes, the son, the daughter, the daughter is from the first wife. Yes, and the first wife and the second wife.
The Shaykh:
Yes, because the wife of a grandfather is a mahram (a relative one may not marry) to her, if she is the wife of a grandfather from the father’s side or the mother’s side. This is because a grandfather is a father. Allah, Mighty and Majestic, says:[An-Nisa 4:22] And the term "father" includes the direct father and includes the grandfather from the mother’s side or the father’s side.
